Google Ads: A Short Guide

1) Google Ads: Core principles #

• Ad Rank matters because it decides if and where your ad shows.
• Relevancy is the engine. Align keyword intent, ad copy, and landing page.
• Ads + UX = better results. Faster pages, clear offers, and strong trust signals improve quality and conversion.

2) Account structure (tree model) #

• Account = Ground: billing, users, shared assets.
• Campaigns = Trees: budgets, geo, languages, networks, bidding goals.
• Ad groups = Branches: tight themes of closely related queries.
• Ads = Leaves: messages tailored to the branch theme and the user intent.

3) Relevance and UX checklist #

• Map keywords to clear intent buckets: informational, comparison, transactional.
• Write copy that mirrors the searcher's phrasing. Use the primary keyword in H1, title tag, and ad headlines when natural.
• Promise in the ad what the page delivers. Keep the same offer, price, and CTA.
• Speed and clarity: under 2.5s LCP, simple forms, visible proof (reviews, badges).

4) Ad Rank and Quality components #

• Ad Rank = bid × quality factors + context and thresholds.
• Quality drivers: expected CTR, ad relevance, and landing page experience.
• Context: device, location, time, query meaning, competition, and the expected impact of assets.
• Improve Ad Rank without raising CPC:
  • Tighten ad group themes.
  • Add 8 to 12 unique headlines and 3 to 4 descriptions in RSAs. Pin only when required.
  • Use relevant assets: sitelinks, callouts, structured snippets, images, lead form if suitable.
  • Align pages to intent and speed.

5) Search Impression Share (SIS) #

• Definition: how often your ad showed compared to how often it was eligible to show.
  • SIS = impressions ÷ eligible impressions.
• Track causes of missed impressions:
  • Search Lost IS (Budget): limited budget.
  • Search Lost IS (Rank): bid or quality not high enough.
• Practical fixes:
  • If Budget is the constraint: reallocate to best campaigns, add dayparting, or raise budget if CPA/ROAS is healthy.
  • If Rank is the constraint: improve quality signals and raise bids where profitable.

6) Bidding guidance (simple) #

• Lead gen with defined CPA goal: Max Conversions with target CPA after enough conversions.
• Ecommerce or clear values: Max Conversion Value with target ROAS.
• Prospecting tests or thin data: Max Clicks or Max Conversions without a target during learning, then add targets.

7) Ad group and copy rules of thumb #

• 1 theme per ad group. 5 to 20 tightly related keywords.
• 1 RSA active per ad group, plus at least 1 spare variant for testing.
• Include primary keyword in H1 and at least one headline. Use a clear CTA and unique value.
• Use negative keywords to protect themes.

8) Weekly operating cadence #

• Queries: mine Search Terms and add negatives.
• SIS triage: identify budget vs rank losses.
• RSA asset report: add unique headlines, remove underperformers.
• Landing pages: check speed, offer clarity, and form friction.
• Budgets: shift to the best CPA or ROAS.
• Experiments: keep one controlled test at a time.

9) Quick glossary #

• Ad Rank: auction score that sets position and eligibility.
• Quality Score proxy: expected CTR, ad relevance, landing page experience.
• Search Impression Share: shown vs eligible.
• Lost IS (Budget/Rank): missed impressions due to budget or rank.
