Google Ads Search cheat sheet

Ad Rank = Max CPC bid × Quality Score + expected impact of ad assets, formats, and other auction signals; it decides whether an ad enters the auction and where it appears.

Quality Score is reported on a 1–10 scale and is composed of expected CTR, ad relevance, and landing page experience; it is diagnostic rather than a live auction input.

Actual CPC is approximately (Ad Rank of the ad below ÷ your Quality Score) + $0.01, and it can never exceed the keyword's Max CPC.

A separate auction runs for every search query; keywords, negatives, bids, budgets, and real-time quality signals are evaluated at query time.

Match types: exact match [keyword], phrase match "keyword", and broad match keyword; negative keywords use the same three syntaxes.

Search campaigns can serve on Google Search, Search Partner sites, Shopping surfaces, Google Maps, and Display when the corresponding network settings are enabled.

Ad assets (formerly extensions) raise Ad Rank through expected impact and are not billed separately; clicks on them are charged only where a click charge applies.

Higher expected CTR and relevance allow a lower bid to achieve the same Ad Rank, which lowers the price paid per click.

Budget is set at the campaign level; Google may spend up to 2× the daily budget on a given day but will not exceed 30.4× the daily budget over a calendar month.

Campaign-level settings include bid strategy, networks, locations, languages, ad schedule, device targeting, and audience segments.

Location targeting offers 'presence or interest' (default) versus 'presence' only, which restricts ads to people physically in the targeted area.

Tightly themed ad groups are the standard structure; a common convention is roughly 5–20 closely related keywords per ad group with matching ad copy.

Negative keyword lists are stored at the account (shared library) level and applied to campaigns; campaign-level negatives and ad group negatives further narrow traffic.

Smart Bidding strategies require active conversion tracking; without conversion data the account can only use click- or impression-based strategies.

Drafts and experiments let changes be staged and tested on a traffic slice before being applied to the live campaign.

Change history records every edit with timestamp, user, and old/new values, making it the first diagnostic for unexplained performance shifts.

A Search campaign needs at least one ad and at least one keyword or keyword source to serve impressions.

Responsive search ads accept up to 15 headlines of 30 characters each and up to 4 descriptions of 90 characters each.

Display URL paths allow up to two fields of 15 characters each appended to the final URL's domain.

Pinning a headline or description forces it into a fixed position and reduces the system's ability to test asset combinations.

Ad strength is rated Poor, Average, Good, or Excellent and reflects asset quantity, uniqueness, relevance to keywords, and coverage.

Asset character limits: sitelink text 25, sitelink description lines 35 each, callouts 25, structured snippet header and values 25.

The display URL domain must match the final URL domain; path text may differ but must accurately reflect the landing page.

Ad policy prohibits excessive capitalization, gimmicky punctuation, unclear pricing, and misleading offers; violations cause disapproval rather than lower rank.

Ad rotation 'Optimize' favors ads predicted to perform better, while even rotation options are limited and generally not recommended for testing.

Impression shortfall is diagnosed with 'Search lost IS (budget)' for budget limits and 'Search lost IS (rank)' for Ad Rank limits.

Bid adjustments multiply rather than add: a +20% device adjustment combined with a +10% location adjustment yields 1.2 × 1.1 = 1.32× the base bid.

Target CPA and Target ROAS are Smart Bidding strategies that set bids per auction to hit the target; Google recommends roughly 30 conversions in 30 days for tCPA and 50 for tROAS.

Maximize conversions and Maximize conversion value spend the full budget efficiently; adding a target CPA or target ROAS constrains them.

Target Impression Share bids toward a chosen share (Absolute top, Top of page, Anywhere on page) and suits visibility goals rather than efficiency goals.

Portfolio bid strategies apply one shared strategy, and optionally a shared budget, across multiple campaigns.

Seasonality adjustments inform Smart Bidding of an expected conversion-rate change for a short window of up to 7 days, such as a promotion.

Manual CPC sets bids at keyword level and honors bid adjustments, giving full control but no per-auction bid adaptation.

Each conversion action has a count setting (Every or One), a click-through window (30 days by default), and a view-through window (1 day by default where applicable).

Attribution models available include last click, first click, linear, time decay, position-based, and data-driven, which is the default for most conversion actions.

Primary conversions are used by bidding strategies; secondary conversions are reported for observation and do not influence Smart Bidding.

The search terms report lists the actual queries that triggered ads, enabling irrelevant queries to be added as negatives and matched to keyword themes.

Conversion value can be static per action, dynamic via a value parameter, or adjusted by value rules based on location, device, or audience.

Experiments split traffic between a control and a variant to measure the incremental effect of a change before full rollout.

Optimization score (0–100%) summarizes the estimated impact of open recommendations and is not a measure of account profitability.

When GA4 conversions are imported, they should not duplicate native Google Ads conversion actions, or bidding signals and reporting will double count.
