Regex for SEO

 Simple regex cheat sheet

Start inside Google Search Console:

👉 Go to Performance → Queries → Filter → Custom (Regex)

Now use these regex filters to uncover keywords that actually move the needle:

1. Short-Tail Queries (1–2 words)

^[^\s]+(\s[^\s]+)?$ 

2. Medium-tail keywords

^\S+(?:\s+\S+){2,3}$

3. Long-Tail Queries (5+ words)

^\S+(?:\s+\S+){4,}$

4. Question Keywords

^(what|why|how|where|when|who|can|is|are|do|does|should|which)\b

5. Blog-Style Keywords

^(how to|best|guide|tips|ideas|review|top|learn|examples|benefits)\

6. Buy-Intent / Commercial Queries

^(buy|purchase|price|cost|hire|near me|services?|company)\b

Imp Google Ads QA

🔥 Quality Score

QS is driven by Ad Relevance, Expected CTR, and Landing Page Experience.

• Tightening keyword → ad → landing page alignment
• Writing intent-specific ad copy
• Improving LPX with UX team (page speed, mobile UX, relevance)
• Removing keywords hurting CTR
• Lowering bounce rate through LP testing
• Adding high-intent negatives to improve expected CTR.”

🔥 How do you manage a large-scale search account daily?

Every day I run the account using an algorithmic routine:

• Auction checks – Ad Rank, IS, rank drops
•  Efficiency filters – identify non-converting queries/keywords
• Bid architecture – adjust Target ROAS or CV based on volume goals
• Query mining – add incremental keywords that show strong product-to-query alignment
• LPX audits – identify pages hurting Quality Score
• Performance stabilization – ensure signals (conversions, budgets, seasonality) are consistent for Smart Bidding.

🔥 Impression Share Diagnostic Framework

Lost IS (Rank) means:

• Low bids
• Low QS
• Competition increased
• Ad Rank issues

How you respond:

• Increase bid or loosen TROAS
• Improve QS components
• Tighten match types
• Improve LPX

🔥 How do you improve LS (Search Lost IS) Rank?

• Increase bids
• Lower TROAS
• Improve QS
• Reduce fragmentation
• Improve LPX

🔥 Traffic Purification Loop

• Identify bad queries/keywords

1. Low CTR → relevance issue
2. High CPC + low value → cost pressure
3. Low expected CTR → hurting QS
4. Conversions < threshold

• Pause / lower bids
• Monitor recovery signs

1. Quality Score improvement
2. CTR improvements
3. ROAS improvement

• Reinstate with small budgets
• Scale if stable

🔥 RCA (Root Cause Analysis) framework

Step 1: Identify the symptom

• ROAS drop
• CPC spike
• Click drop
• Conversion drop
• IS loss
• QS drop

Step 2: Check auction metrics

• CPC
• IS Lost Rank
• Ad Rank
• Top vs Absolute Impression Share
• Overlap rate with competitors

Step 3: Check user-level metrics

• CTR
• CVR
• Bounce rate
• Device segmentation
• Audience segmentation

Step 4: Check platform-side factors

• Bid strategy learning
• Conversion signal delays
• Budget limits
• LPX issues

Step 5: Implement a corrective action

• Adjust bids
• Improve ads
• Add negatives
• Update landing page
• Adjust TROAS
• Expand keywords

🔥 What is Keyword Intent Mapping?

Aligning queries to correct match types and campaigns based on intent level:

• High-intent → exact match
• Mid-intent → phrase
• Discovery → broad

This increases QS, improves control, and strengthens ad relevance.”

🔥 How do you ensure Smart Bidding stability?

• Single source of truth conversion
• No conflicting bid changes
• Stable budgets
• Long-enough learning windows
• Consistent campaign signals
• No over-fragmentation

🔥 Smart Bidding

Target ROAS (TROAS)

• When to loosen (to increase volume)
• When to tighten (to improve efficiency)
• Why TROAS needs consistent signals
• Importance of conversion lag analysis

Maximize Conversions / Conversion Value

• Used for scaling during budget-free environments
• Best for early learning or rapid share acquisition

Key phrase to use:

“Smart Bidding only works if you maintain signal purity. My job is to protect the algorithm from noise.”

🔥Deep Auction-Level Explanation

1️⃣ Maximize Conversions (or Max Conversion Value)

Best when the goal is:

• Maximum traffic & reach
• Enter more auctions
• Win impressions aggressively
• Collect signals quickly
• Launch new campaigns/products

Why it works well in auctions:

• It removes efficiency constraints
• Algorithm bids more aggressively
• You get higher impression share
• Good for unstable environments with low data
• Smart Bidding tries to maximize clicks/conversions within your budget

Downside:

• CPC increases
• ROAS becomes unpredictable
• Not suitable for mature accounts

2️⃣ Target ROAS (tROAS)

Best when the goal is:

• Efficiency
• Maintaining profitable auctions
• Defending ROAS
• Controlling expensive keywords
• Running large-scale accounts with stable conversion data

Why it works best in auctions for profitability:

• Algorithm bids only when predicted value ≥ ROAS threshold
• Eliminates low-value auction entries
• CPC is controlled more tightly
• Search Lost IS (Rank) may increase (because you're selective), but ROAS improves
• Works extremely well in stable, high-volume campaigns

Downside:

• Restricts volume
• Sometimes avoids competitive auctions
• Requires strong, consistent conversion signal density
• Not ideal for new keywords or new markets

🔥How Google’s Auction Reacts to Each Strategy

Depends on business goal, but primary KPIs: CTR CPC Quality Score Conversion Rate Cost per Conversion ROAS Impression Share Search Lost IS (budget & rank) 🔥 What is Impression Share? Impression Share = % of total possible impressions your ads actually got. Types: Search Impression Share Search Lost IS (Budget) Search Lost IS (Rank) If lost due to budget, I scale budget. If lost due to rank, I improve QS or bid. 🔥 What is the difference between Broad, Phrase & Exact match? Broad: Wide reach, AI-driven relevance, good for discovery Phrase: Medium control, matches close meaning Exact: Tight control, high intent I usually begin with broad + smart bidding, then refine using search terms. 🔥 Explain negative keywords. How do you use them? Negative keywords prevent ads from showing on irrelevant queries. I add them: From Search Terms Report Using common exclusions (free, jobs, meaning, PDF etc.) At Ad Group, Campaign, or List level Negatives improve CTR, CPC, and Quality Score. 🔥 How do you measure success in Google Ads? Success = alignment of KPIs with business goals. I measure: Leads quality & CPL Revenue & ROAS CAC vs LTV Conversion rate trends Funnel performance (Search → Remarketing → Conversion) 🔥 What are the main extensions you use? Sitelinks Callouts Structured Snippets Call Extensions Location Extensions Image Extensions Price Extensions These increase CTR and improve Ad Rank. 🔥 How do you optimize a campaign that is not performing well? Check conversion tracking Review search terms & add negatives Improve ad copy CTR Fix landing page issues Re-evaluate bid strategy Pause wasteful keywords Analyze device/location performance Test new creatives I optimize based on data, not intuition. 🔥 How do you handle high CPA? Improve landing page Add high-intent keywords Add more negatives Switch to tCPA after 30+ conversions Improve ad relevance Cut waste from low-performing audiences/locations/devices CPA drops once quality improves. 🔥 What is your approach to scaling a Google Ads account? Expand winning keywords Add similar audiences Launch YouTube remarketing Increase daily budgets gradually (10–20%) Duplicate top campaigns for performance testing Add new match types Create value-based campaigns (tROAS) Scaling is methodical, not aggressive.
