Responsive search ads: best practices for Indian advertisers

Responsive Search Ads replaced Expanded Text Ads as the default in Google Ads. If you are still thinking in terms of writing one fixed ad with three headlines and two descriptions, you need to update how you approach this. RSAs give you up to 15 headlines and 4 descriptions, and Google mixes and matches them into combinations shown to different searchers.

The catch is that RSAs are only as good as the assets you feed them. Garbage in, garbage out.

Write truly different headlines, not variations of the same thing

The most common mistake is writing 15 headlines that all say approximately the same thing in different words. Google cannot create meaningful variety if every headline is a version of "Best digital marketing agency in India".

Your 15 headlines should cover distinct themes: your primary offer, your price or price range, your differentiator, your geographic coverage, a social proof claim, an urgency element, a risk-reduction statement, and your call to action. That is eight distinct angles. Fill the rest with specific benefit statements.

For a Bangalore-based IT training institute, a good headline set might include: "Python courses in Bangalore", "Fees from ₹18,000", "100% placement assistance", "Batches starting every month", "Weekend and weekday batches", "Live projects included", "Trained 4,000+ students", "Refund if not satisfied". Each of these serves a different searcher intent.

Use pinning strategically, not habitually

Pinning forces a headline to appear in a specific position. Position 1 is always shown, position 2 is usually shown. Pinning is useful when you must control messaging for legal, brand, or clarity reasons.

Do not pin every headline. Pinning too many options defeats the purpose of RSAs, which is to let Google test combinations. If you pin five headlines, Google cannot optimise. Pin one or two at most, typically your primary brand or product claim.

For government tender businesses or pharmaceutical companies where specific claims must appear, pinning is essential. For most businesses, keep pinning to a minimum.

Write descriptions that complement, not repeat

Your four description lines should add information not already covered in your headlines. If your headlines mention price and location, use descriptions for process, social proof, and calls to action.

A description that works for most Indian service businesses: "Talk to our team before committing. Free 20-minute consultation available. Call or WhatsApp us now." That sentence covers low pressure, free access, and preferred contact method, all of which reduce friction.

Write each description to work standalone. Google may show only one. Make sure each one is useful on its own without needing another description for context.

Check the Ad Strength indicator but do not chase it

Google's Ad Strength rating (Poor, Average, Good, Excellent) gives you feedback on how well your RSA is set up. Aim for Good or Excellent by having enough unique headlines and including keywords naturally.

But do not stuff keywords into every headline just to get to Excellent. I have seen clients with Excellent Ad Strength that converted terribly because the headlines were awkward keyword insertions rather than natural copy. The metric is a proxy, not the goal.

Check which combinations Google is actually serving under the "Combinations" tab in your RSA editor. If you see the same headlines repeatedly, your assets are probably too similar.

Local relevance still matters

RSAs work better when localised. For a business targeting multiple cities, build separate RSAs per campaign or ad group with city-specific headlines. "Accounting software training in Hyderabad" will outperform "Accounting software training in India" for a Hyderabad searcher.

If you are targeting India broadly, include a mix of regional indicators. "Trusted by 1,200 businesses across India" is more credible than "Best in India" because it is specific.
