What is Google Ads Search Ads?

Google Ads Search Network ads are text ads shown with a "Sponsored" label at the top and bottom of the results page when a user searches on Google. The advertiser pays only when the ad is clicked (cost per click, CPC). The power of the search network is simple: your ad is shown to the person who is searching for exactly what you sell, at the exact moment they need it.

How Do Search Ads Work?

Every time a search happens, Google runs an auction in milliseconds between advertisers who want to appear for that query. Ranking is not decided by bid alone; ad quality matters just as much. Google's Ad Rank is roughly built from:

• Bid: The maximum you are willing to pay for a click.
• Expected click-through rate: How likely your ad is to be clicked.
• Ad relevance: How well the copy matches the query.
• Landing page experience: Speed, mobile friendliness and whether the page truly delivers what was searched.

That is why a high-quality ad can appear above a higher-bidding competitor at a lower cost. In search advertising, structure wins as much as budget.

Keyword Match Types

Exact match [keyword] is the narrowest and most controlled; phrase match "keyword" opens up to close variations; broad match gives Google's AI the most room and performs well when combined with Smart Bidding. And the reverse matters too: negative keywords (such as "free" or "second hand") keep your ads out of searches you don't want and protect your budget.

Responsive Search Ads (RSA)

The standard search ad format today is the responsive search ad: you provide up to 15 headlines and 4 descriptions, and Google automatically assembles the best combination for each search. Spreading the searched keyword, your price/benefit message and a call to action across the headlines gives the system material to test. Assets (formerly extensions) — sitelinks, callouts, call, location and price assets — significantly increase your ad's footprint and click-through rate.

Smart Bidding and AI

As of 2026, most search campaigns are run with Smart Bidding rather than manual bids: target CPA, target ROAS or maximize conversions. For these strategies to decide well, conversion tracking must be set up flawlessly; without real goals such as sales, forms and calls being measured, Smart Bidding runs blind. Performance Max complements the search network by reaching all Google surfaces (Search, Display, YouTube, Gmail, Discover) from a single campaign; best practice is to keep your brand and core search campaigns while using Performance Max to capture additional demand.

Practical Tips for Success

• Split campaigns by product/service groups; keep a single theme per ad group.
• Review the search terms report regularly and grow your negative keyword list weekly.
• Match the landing page to the ad: someone searching for "coffee machine repair" should land on that service page, not your homepage.
• Bid on your own brand name so competitors cannot sit above your brand searches.
• Optimise daily in the first weeks, then at least weekly.
