The 15 Most Common Google Ads Mistakes and How to Avoid Them

In my experience: many Google Ads beginners waste a large share of their budget through avoidable mistakes. This guide shows you the 15 most critical errors – and most importantly, how to avoid them to optimize your budget.

Mistake #1: No Conversion Tracking

The Problem

Symptom: You see clicks and impressions, but don't know if anyone is buying or requesting quotes.

Why it's fatal: Without conversion tracking, you're optimizing blind. You don't know:

• Which keywords are working
• Which ads are converting
• What CPA is acceptable
• Whether campaigns are profitable

Reality: in my experience, a large share of beginner accounts have NO working tracking.

The Solution

Minimum Setup (30 minutes):

Step 1: Create Conversion Action

Google Ads → Tools → Conversions → + New Conversion
→ Website → Form submission/Purchase
→ Enter value (average order value)
→ Copy tracking code

Step 2: Implement Tag Manager

Google Tag Manager → New Tag → Google Ads Conversion Tracking
→ Insert Conversion ID & Label
→ Trigger: Thank you page or Form Submit
→ Publish

Step 3: Test!

• Complete test order
• Check if conversion appears in Google Ads

Advanced: ✅ Offline Conversions (for phone inquiries → CRM) ✅ Call Tracking (for calls) ✅ E-Commerce Tracking (for cart value) ✅ Enhanced Conversions (for better attribution)

Investment: €0-500 setup (depending on complexity) ROI: Priceless – without tracking you can't optimize!

Mistake #2: Broad Match Without Control

The Problem

What is Broad Match? Google shows your ad for "related searches."

Example:

• Your keyword: "running shoes"
• Google shows for:
  • ✅ "Nike running shoes buy" (good)
  • ⚠️ "women's running shoes" (ok, if you sell all genders)
  • ❌ "running shoes repair" (bad – service, not product)
  • ❌ "used running shoes" (bad – you sell new)
  • ❌ "DIY running shoes" (bad – DIY)

Budget waste: 40-60% with uncontrolled Broad Match!

The Solution

Option A: Use Exact Match Types

[women's Nike running shoes] → Exact Match
"buy running shoes" → Phrase Match

Advantage: Full control Disadvantage: Less reach

Option B: Broad Match WITH aggressive Negative Keywords

Only for advanced accounts with Smart Bidding!

Starter Negative Keywords List (100+ terms):

-free, -gratis
-diy, -tutorial, -guide
-used, -secondhand
-repair, -fix
-jobs, -job, -career, -training
-wiki, -wikipedia, -definition
-images, -picture, -photos
-test, -review (unless you sell award winners)
-cheap, -budget (for premium products)

Weekly Maintenance:

1. Open Search Terms Report
2. Mark irrelevant terms as negative
3. Add 10-20 new Negative Keywords per week

For Beginners: Start with Exact & Phrase Match, expand to Broad later.

---

Mistake #3: One Ad Group for Everything

The Problem

Typical Beginner Setup:

Campaign: "Running Shoes"
  Ad Group: "All Running Shoes"
    Keywords:
    - running shoes
    - women's running shoes
    - men's running shoes
    - Nike running shoes
    - Adidas running shoes
    - trail running shoes
    - marathon shoes

    Ad:
    "Buy Running Shoes | Great Selection"

Problem:

• Keyword "Nike running shoes" → Ad shows "Running Shoes" (generic)
• Keyword "Trail running shoes" → Ad shows "Running Shoes" (not specific)
• Result: Low CTR, low Quality Score, high CPCs

Quality Score: 3-4/10 instead of 8-9/10 CPC: 2x-3x higher than necessary!

The Solution

SKAGs (Single Keyword Ad Groups) or themed clusters

Optimized Structure:

Campaign: "Running Shoes"

  Ad Group: "Nike Running Shoes"
    Keywords:
    - [Nike running shoes]
    - [Nike running shoes women]
    - [Nike running shoes men]

    Ad:
    "Buy Nike Running Shoes | Official 2025 Models"

  Ad Group: "Trail Running Shoes"
    Keywords:
    - [trail running shoes]
    - [trail shoes]
    - [trail running footwear]

    Ad:
    "Trail Running Shoes | For Demanding Terrain"

Result:

• ✅ Keyword in ad headline → higher CTR
• ✅ Higher relevance → better Quality Score
• ✅ Lower CPCs (30-50% cheaper!)

Rule of thumb: Max. 5-10 closely related keywords per ad group.

---

Mistake #4: Poor Ad Copy

The Problem

Typical Beginner Ad:

Buy Running Shoes
We sell running shoes.
Great selection. Order now.
example.com/running-shoes

Problems: ❌ Generic (could be anyone) ❌ No USPs (Unique Selling Points) ❌ No trust (no social proof) ❌ Weak CTA ("Order now") ❌ No urgency

CTR: 1-2% (poor)

The Solution

Formula for High-Converting Ads:

Headline 1: Keyword + Benefit Headline 2: USP or Social Proof Headline 3: Offer or Urgency

Description 1: Detailed Benefit + Trust Description 2: CTA + Additional Info

Optimized Ad:

Headline 1: Running Shoes 2025 | Free Shipping over €50
Headline 2: 4.9★ from 10,000+ Runners | Premium Quality
Headline 3: 20% Off Best Sellers Now

Description 1: Premium running shoes from Nike, Adidas & more.
Personal advice. 30-day return policy.

Description 2: Order now and get free shipping +
complimentary socks worth €15. Limited time only!

example.com/running-shoes

Elements that work: ✅ Keyword in title ✅ Social proof (reviews, customer count) ✅ Numbers (discount, shipping costs) ✅ Trust (return policy, guarantee) ✅ Urgency (limited, short time only) ✅ Bonus (free socks)

CTR: 6-12% (good to excellent)

Testing Tools:

• Google Ads Responsive Search Ads (3-5 variants per element)
• A/B Testing of headlines

---

Mistake #5: Wrong Landing Page

The Problem

Typical Mistake:

• Keyword: "buy Nike Air Zoom Pegasus 40"
• Ad: "Nike Air Zoom Pegasus 40 | Order Now"
• Landing Page: Homepage with all 500 products

Result:

• Visitor has to search
• Friction in purchase process
• 80-90% Bounce Rate
• Conversion Rate: 0.5-1%

Budget waste: At €3 CPC and 0.5% CR = €600 CPA!

The Solution

Rule: Keyword → Ad → Landing Page must match

Optimal Landing Page:

Keyword: "buy Nike Air Zoom Pegasus 40"
Ad: "Nike Air Zoom Pegasus 40 | 20% Off"
Landing Page: Nike Air Zoom Pegasus 40 Product Page
  - Large product images
  - Clear headline: "Nike Air Zoom Pegasus 40"
  - 20% off banner
  - "Add to Cart" button above the fold
  - Trust elements (reviews, shipping info)
  - Benefit list
  - CTA: "Order now"

Landing Page Optimization: ✅ Load time under 2 seconds ✅ Mobile optimized (60-70% traffic is mobile!) ✅ Clear headline (include keyword) ✅ CTA above the fold ✅ Trust elements (reviews, certificates, guarantees) ✅ Few distractions (no complex menu) ✅ Contrasting CTA button

Conversion Rate Increase: From 0.5% to 3-5% = 6-10x more conversions!

---

Mistake #6: No Mobile Optimization

The Problem

In practice: a large share of Google Ads traffic typically comes from mobile.

Typical mobile website problems: ❌ Slow load time (over 3 seconds) ❌ Not responsive (text too small, buttons too close) ❌ Complicated checkout (too many fields) ❌ Phone number not clickable

Result:

• Mobile Conversion Rate: 0.5-1%
• Desktop Conversion Rate: 3-5%
• You're wasting 60-70% of your budget!

The Solution

Mobile-First Design:

1. Speed Optimization

• Compress images (WebP format)
• Lazy loading
• Use CDN
• Goal: Load time under 2 seconds

Tool: Google PageSpeed Insights

2. Tap-friendly Design

• Buttons at least 48x48px
• Enough spacing between links
• Large fonts (min. 16px)

3. Simplified Checkout

• Enable guest checkout
• Fewer form fields (essentials only)
• Support autofill
• Mobile payment (Apple Pay, Google Pay)

4. Click-to-Call

• Phone number prominent
• As clickable link (<a href="tel:...">)
• Call extension in Google Ads

5. Mobile-Specific Ad Copy

Mobile Ad:
"Call Now: 0800-123456 | 24h Service"
→ With call extension

Result: Mobile CR increases from 0.5% to 2-3% = 4-6x more conversions

---

Mistake #7: Budget Waste Through Wrong Geo-Targeting

The Problem

Scenario 1: Local business advertising nationwide

Example: Dentist in London advertising across the UK

• Budget: £1,000
• Clicks from all UK: 200 clicks
• Clicks from London (relevant): 20 clicks
• Waste: 90% of budget!

Scenario 2: E-Commerce without geo analysis

You only ship in the UK, but Google shows in Ireland/EU

• 15-25% budget goes to non-deliverable regions

The Solution

For local businesses:

Setup:

Google Ads → Campaign → Locations
→ Enter your radius:
  - London, 25km radius
→ Or specific neighborhoods

Advanced: Geo-Bid Adjustments

Check location performance:
- London Center: CPA £40 → +30% bid
- London Outskirts: CPA £60 → +0% bid
- 50km+ radius: CPA £120 → -50% bid or pause

For E-Commerce / Services:

1. Analysis by Region

Google Ads → Locations Report
→ Sort by CPA or ROAS

Example Results:

• London: CPA £35, ROAS 450%
• Manchester: CPA £42, ROAS 380%
• Scotland: CPA £95, ROAS 180%

Action:

• +20% bid London
• +0% bid Manchester
• -40% bid Scotland or exclude

2. Exclude unprofitable regions

Campaign → Locations → Exclusions
→ Add regions/cities

Budget Savings: 20-40%

Mistake #8: No Ad Extensions

The Problem

Ad WITHOUT Extensions:

Buy Running Shoes | Great Selection
Premium running shoes from top brands. Free shipping.
example.com

Space: 3 lines, 25% screen (Mobile)

Ad WITH Extensions:

Buy Running Shoes | Great Selection
Premium running shoes from top brands. Free shipping.
example.com

[Men] [Women] [Trail] [Marathon]
📍 London, Oxford Street 1
☎ 0800-123456
★★★★★ 4.9 (1,200 reviews)

Space: 8 lines, 60% screen

CTR Increase: +10-30% through extensions!

The Solution

These extensions you should ALWAYS use:

1. Sitelink Extensions (4-6 links)

- Men's Running Shoes
- Women's Running Shoes
- Sale: 20% Off
- Customer Reviews

2. Call Extensions

☎ 0800-123456 (toll-free)
→ Especially important for services

3. Location Extensions

📍 London, Oxford Street 1
→ Link Google My Business

4. Callout Extensions

Brands: Nike, Adidas, Asics, Brooks
Services: Free Shipping, 30 Day Returns, Personal Advice

5. Rating Extensions

★★★★★ 4.9 out of 5 (1,200 reviews)
→ Only with 3.5+ star average

6. Price Extensions (for E-Commerce)

Nike Air Zoom: from €129
Adidas Ultraboost: from €159
Asics Gel: from €119

7. Image Extensions

Product images directly in the ad
→ Especially for Shopping campaigns

Setup Time: 30-45 minutes one-time Impact: +15-35% higher CTR = lower CPCs!

Mistake #9: Leaving Campaigns on Autopilot

The Problem

Typical Scenario:

• Month 1: Campaigns set up, running
• Month 2-6: "It's running, I don't need to do anything"
• Result: Performance gradually deteriorates

Why:

• Competitors optimize → Your position drops
• New keywords emerge → Budget goes away
• Search behavior changes
• Seasonal effects (e.g., Christmas, summer)

Performance Drop: 20-40% over 6 months without optimization

The Solution

Weekly Optimization (30-60 min):

Week 1: Search Terms Report

Google Ads → Keywords → Search Terms
→ Sort by impressions

Tasks: ✅ Mark new irrelevant search terms as negative (10-20 new) ✅ Add well-performing search terms as keywords ✅ Identify wasted clicks

Budget Savings: 10-20% through aggressive Negative Keywords

Week 2: Bid Optimization

Google Ads → Keywords → Sort by CPA/ROAS

Tasks: ✅ Profitable keywords: Bid +20-30% ✅ Unprofitable keywords (CPA > target): Bid -30% or pause ✅ Keywords without conversions after 30 days: Pause

Week 3: Ad Performance

Google Ads → Ads → Sort by CTR

Tasks: ✅ Ads with CTR below 3%: Rewrite or pause ✅ Test new ad variants (at least 2 per group) ✅ Identify winner ads and replicate

Week 4: Budget Allocation

Google Ads → Campaigns → Sort by ROAS/CPA

Tasks: ✅ Profitable campaigns: Budget +20-30% ✅ Unprofitable campaigns: Budget -30% or pause ✅ Test new campaign ideas (10-20% budget for tests)

Monthly: Strategy Review

• Overall performance vs. goals
• Competitor monitoring
• Identify new opportunities
• Start landing page tests

Time Investment: 2-4 hours/month Performance Improvement: +30-60% over 3 months

---

Mistake #10: Smart Bidding Without Data

The Problem

Scenario:

• Day 1: Google Ads account created
• Day 2: Smart Bidding ("Maximize Conversions" or "Target CPA") activated
• Week 1-4: Algorithm "learns" with your money
• Result: 2-3x higher CPAs than necessary

Why: Smart Bidding needs at least 30-50 conversions per month for meaningful optimization.

With 10 conversions/month: Algorithm guesses more than it optimizes.

The Solution

Phase 1: Manual Bidding (Month 1-2)

Campaign → Bidding Strategy → Manual CPC
→ Optional: Enable Enhanced CPC (small optimizations)

Advantage:

• Full control
• You learn what keywords are worth
• No budget waste through "learning"

Phase 2: Enhanced CPC (Month 2-3)

Bidding Strategy → Manual CPC with Enhanced CPC

Advantage:

• Still in control
• Google optimizes ±30% in real-time
• Smooth transition

Phase 3: Portfolio Strategy (from 50+ conversions/month)

Tools → Bidding Strategies → Create Portfolio Strategy
→ "Maximize Conversions" or "Target CPA"
→ Add multiple campaigns

Advantage:

• More data for algorithm (combined conversions)
• Better performance than individual campaigns

Phase 4: Campaign-Level Smart Bidding (from 100+ conversions/month per campaign)

Campaign → Bidding Strategy → Target CPA or Target ROAS

Timeline:

• Month 1-2: Manual (Learning)
• Month 3-4: Enhanced CPC (Transition)
• Month 5+: Smart Bidding (Automation)

CPA Improvement: Properly implemented Smart Bidding can reduce CPA by 20-40% – but only with enough data!

Mistake #11: Display Ads for Beginners

The Problem

Typical Beginner Setup:

• Budget: €1,000/month
• Split: €500 Search + €500 Display
• Display Results:
  • 100,000 impressions
  • 300 clicks (0.3% CTR)
  • 3 conversions (1% CR)
  • CPA: €167

Search (for comparison):

• 250 clicks
• 8 conversions (3.2% CR)
• CPA: €63

Problem: Display is 2-3x more expensive for cold traffic, needs more budget for profitability.

The Solution

For Beginners (Budget under €3,000):

Rule: ❌ No Display for Cold Traffic

Instead:

• ✅ 100% budget on Search Ads
• ✅ Display Remarketing (only for website visitors)

Display Remarketing Setup:

New Campaign → Display → Website Traffic
→ Audience: Website Visitors (last 30 days)
→ Budget: 10-20% of total budget

Why better:

• CPC: €0.20-0.80 (instead of €1-3)
• CTR: 1-3% (instead of 0.1-0.5%)
• CR: 3-8% (instead of 0.5-2%)

For Advanced (Budget over €5,000):

Display Cold Traffic makes sense for:

• Brand awareness
• Multi-touch customer journeys
• Visual products (fashion, interior)

But: Separate budget pool, don't mix with Search!

Budget Split:

• Search: 60-70%
• Shopping/PMax: 20-30%
• Display Remarketing: 10%
• Display Cold Traffic: 0-10% (only if profitable)

---

Mistake #12: Too Many Campaigns Simultaneously

The Problem

Typical Beginner Account (Budget: €1,500/month):

• Campaign 1: Search Ads (€300)
• Campaign 2: Shopping Ads (€300)
• Campaign 3: Display Ads (€300)
• Campaign 4: YouTube Ads (€300)
• Campaign 5: Performance Max (€300)

Result per campaign:

• 50-150 clicks/month
• 1-5 conversions/month
• Too little data for optimization

The Solution

Focus: 1-2 campaign types until profitable

Recommended Sequence:

Phase 1 (Budget €500-2,000): Search Ads only

• 100% budget
• Focus on most profitable keywords
• Optimize until CPA < target

Phase 2 (Budget €2,000-5,000): Search + Shopping/PMax

• Search: 70%
• Shopping/PMax: 30%
• Remarketing: 10% of total

Phase 3 (Budget €5,000+): Multi-Channel

• Search: 40-50%
• Shopping/PMax: 30-40%
• Remarketing: 10-20%
• Display/YouTube: 10-20% (Testing)

Rule of thumb: Each campaign should have at least €500/month budget – otherwise it's wasted.

---

Mistake #13: Ignoring the Competition

The Problem

Scenario:

• Month 1: Your campaigns run, CPA €50
• Month 3: Competitors launch aggressive campaigns
• Month 4: Your CPA rises to €85
• You: "What happened?"

Reality: Google Ads is an auction. When competition increases, prices rise.

The Solution

Competitor Monitoring:

1. Auction Insights Report

Google Ads → Campaigns → Auction Insights

Metrics:

• Impression Share: How often do you appear vs. competition?
• Overlap Rate: How often do you appear together with competitor X?
• Outranking Share: How often do you rank higher?
• Top of Page Rate: How often are you in top position?

Analysis:

• Identify new competitors
• Recognize dominant players
• Understand your position

2. Manual Competitor Research

Method: Google your keywords and analyze

"Google Ads agency London" → Who appears?
→ What ad copy do they use?
→ What USPs?
→ What ad extensions?

Learnings:

• Identify best practices
• Find gaps (What are they doing that you're not?)
• Develop differentiation

3. Competitor Landing Page Analysis

Questions:

• What do competitors do better?
• What trust elements do they use?
• How is their pricing positioned?
• What's their USP?

Tools:

• SEMrush (shows competitor keywords & ads)
• SimilarWeb (traffic analysis)
• SpyFu (historical ad data)

Cost: €100-400/month Value: Strategic insights are priceless

---

Mistake #14: No Remarketing Strategy

The Problem

In practice: the vast majority of website visitors don't buy on first visit.

Without Remarketing:

• You pay €3 for a click
• Visitor looks around
• Leaves website
• You never see them again
• €2.88 wasted (96% × €3)

With €1,000 budget: You waste €960 on visitors you never see again!

The Solution

Remarketing Setup (30 min):

Step 1: Create Audiences

Google Ads → Audience Manager
→ Website Visitors → New Audience

Segments:
1. All Visitors (last 30 days)
2. Cart Abandoners (visited checkout, no purchase)
3. Product Page Visitors (no purchase)
4. Blog Readers (content interested)

Step 2: Remarketing Campaigns

Option A: Display Remarketing

New Campaign → Display → Website Traffic
→ Audience: Cart Abandoners
→ Budget: 15-20% of total budget

Ad:

"Still thinking? Get 10% Off Now!"
→ Visual: Products they had in cart

Option B: RLSA (Remarketing Lists for Search Ads)

Search Campaign → Audiences → Observation
→ Add Cart Abandoners
→ Bid Adjustment: +50-100%

Why:

• When someone who was already in cart searches again → higher intent
• Justifies higher bids

Remarketing Sequence (Advanced):

Day 1-7: Discount Offer

"10% Off Your Cart!"

Day 8-30: Social Proof

"Over 10,000 happy customers!"
+ Show reviews

Day 31-90: New Angle

"New Arrivals: 2025 Models"

Performance:

• CPC: €0.20-0.80 (90% cheaper!)
• CR: 4-10% (4-5x higher!)
• CPA: €5-20 (instead of €50-150 for cold traffic)

Budget Recommendation:

• Cold Traffic (Search/Shopping): 70-80%
• Remarketing: 20-30%

---

Mistake #15: No Landing Page Tests

The Problem

Typical Scenario:

• Landing page is "done"
• Runs 6 months unchanged
• Conversion Rate: 2%

What if CR was 4%?

Calculation:

• Budget: €3,000/month
• CPC: €2
• Clicks: 1,500

With 2% CR:

• Conversions: 30
• CPA: €100

With 4% CR (achieved through testing):

• Conversions: 60
• CPA: €50

Result: Double the conversions with same budget!

The Solution

Landing Page Testing Program:

Month 1: Baseline

• Current landing page runs
• Document conversion rate
• Analyze user behavior (heatmaps, scroll depth)

Tools:

• Hotjar (heatmaps, session recordings)
• Google Analytics 4 (scroll depth, time on page)
• Microsoft Clarity (free!)

Month 2: Hypothesis

Questions:

• Where do visitors drop off?
• Which elements are ignored?
• Is CTA visible?
• Is mobile UX good?

Test Ideas (by impact):

High Impact Tests:

1. Headline (biggest impact)

   • Current: "Buy Running Shoes"
   • Test: "The Best Running Shoes 2025 | Recommended by Pros"

2. CTA Button

   • Current: "Buy"
   • Test: "Order Now & Get Free Shipping"

3. Trust Elements

   • Test: Show reviews prominently
   • Test: Highlight money-back guarantee

4. Images

   • Test: Lifestyle images vs. product-on-white
   • Test: Video vs. images

Medium Impact Tests: 5. Form Length

• Current: 10 fields
• Test: 5 fields (essentials only)

6. Layout
   • Test: Single-column vs. two-column
   • Test: Long-form vs. short-form

Month 3-6: Continuous Testing

Framework:

• Week 1-2: Test runs (at least 100 conversions for statistical significance)
• Week 3: Analysis
• Week 4: New test setup

4 tests per quarter = 16 tests per year

Realistic Expectation:

• 25% of tests are winners (big improvement)
• 50% neutral
• 25% worse

But: One winner with +30% CR improvement justifies 10 tests!

A/B Testing Tools:

• Google Optimize (free, but being discontinued in 2024)
• VWO (from €200/month)
• Optimizely (from €500/month)
• Unbounce (landing page builder with testing, from €90/month)

DIY Method (without tool):

• Create two versions of landing page
• 50% traffic to version A, 50% to version B
• Compare after 2 weeks

Expected Impact over 12 months:

• Start: 2% CR
• After 12 months testing: 3.5-5% CR
• 75-150% more conversions with same budget!

Frequently Asked Questions About Google Ads Mistakes

What is the biggest mistake with Google Ads?

The biggest mistake is not having working conversion tracking. Without tracking, you can't measure which keywords, ads, or campaigns are profitable. This leads to blind optimization and budget waste of 40-60%. Set up conversion tracking BEFORE your first click.

Why am I wasting so much budget on Google Ads?

Main reasons for budget waste: 1) Broad match keywords without negative keywords (40-60% waste), 2) Poor Quality Score (2-3x higher CPCs), 3) Wrong landing pages (low conversion rate), 4) No mobile optimization (60-70% traffic wasted), 5) Geo-targeting too broad.

How do I prevent Google from spending my budget too quickly?

Set: 1) Daily budget caps in campaign settings, 2) Manual bids instead of Smart Bidding with little data, 3) Aggressive negative keywords (50-100+), 4) Restrict geo-targeting to profitable regions, 5) Ad scheduling for best times only, 6) Exact match instead of broad match.

Should I use Smart Bidding as a beginner?

No. Smart Bidding needs at least 30-50 conversions/month for meaningful optimization. Beginners should start with manual CPC bidding (month 1-2), then Enhanced CPC (month 3-4), and only from month 5+ with sufficient data switch to Smart Bidding.

Why is my Quality Score so low?

Low Quality Score comes from: 1) Keywords not in ad text (low relevance), 2) Too many keywords in one ad group (poor structure), 3) Low CTR (unattractive ads), 4) Poor landing page experience (slow, not relevant). Solution: Focused ad groups with 5-10 thematically similar keywords.

How many keywords should I have per ad group?

Maximum 5-10 closely related keywords per ad group. Beginners often make the mistake of packing 50+ different keywords into one group. This leads to generic ads, low CTR, poor Quality Score, and high CPCs. Better: Thematic clusters with specific ads.

Should I use Display Ads as a beginner?

No. Display ads for cold traffic have 0.1-0.5% CTR and low conversion rates. With budget under €3,000, focus on Search Ads. Only exception: Display remarketing (website visitors only) – that works well with CPC €0.20-0.80 and CR 4-10%.

How often should I optimize my Google Ads campaigns?

Minimum: Weekly 30-60 min for search terms report and negative keywords. Optimal: Bi-weekly for bid adjustments, ad tests, budget shifts. Monthly: Strategy review and larger optimizations. Quarterly: Landing page tests and competitive analysis. Without regular optimization, performance deteriorates by 20-40% over 6 months.
