RSA builder with preview

A responsive search ad, RSA, consists of several headings and descriptions that Google Ads combines to find relevant variants for different searches.

Google Ads allows up to 15 headlines and 4 descriptions. You don't have to fill every slot, but a larger selection of relevant and clearly varied texts gives the system more useful combinations to test. HERE recommends that you aim for at least 8 unique headlines and 3 descriptions as a starting point.

Headlines that say almost the same thing create many combinations without adding new messages. Therefore, for example, mix keywords, concrete benefits, features, offers, trust signals and invitations. Then Google can choose a message that better corresponds to the user's search and situation.

A better ad strength mainly shows that the ad has enough relevant and varied assets to be able to create more useful combinations. It can provide better conditions for reach and relevance, but ad strength is no guarantee of higher click-through rates, more conversions or better profitability.

No. Google's full algorithm is not public and uses signals that the tool cannot see. HERE's score is a transparent estimate based on assets, keyword coverage, variation, angles and pinning.

No. The most important keyword should be in several relevant headings and preferably in at least one description, but excessive repetition makes the ad less varied. The tool helps you see both lack of coverage and when the same wording is used too often.

Pin a headline only when a message must appear in a specific position, for example for legal reasons or to ensure the brand is always shown. Pinning reduces the number of possible combinations and should therefore be used sparingly.

The preview shows examples of possible combinations in desktop and mobile formats. The actual ad may receive a different line break or combination in Google search results depending on screen, search, available space and which assets Google chooses.

Yes. The tool can create a separate CSV file with columns for campaign, ad group, headlines, descriptions, anchors, paths and final URL.

No. The ad is built and analyzed locally in your browser. The content is not sent to HERE when you use the tool. If you create a share link, the draft is stored in the link itself.
