One Responsive Search Ad with three generic headlines is not a test. It is a single guess wearing a format that was built to combine lines. For a catalog ad group, write three or four ads, keep them unpinned unless a legal or offer line must appear, and take every line from the page you are paying to send people to.

Raw prompts produce the opposite: interchangeable headlines, no review count, no material, and a call to action that does not match the button on the page. The ad can be grammatically fine and still be disconnected from the SKU.

What the lines are allowed to say

Pull from the landing page in this order, and stop when you run out of facts:

  • The product or collection noun the ad group was built for, in the words the page uses.
  • A specific proof: a material, a size range, a compatibility note, a rating count that is visible on the page.
  • The commercial fact you can honor: price band, bundle contents, shipping window, warranty.
  • The action the page actually offers. If the button says "Choose size," do not write "Book a fitting" unless that is a real path.

Write the variants so they are different facts, not synonyms. "Waterproof trail shoe," "Ready for wet rock," and "Built for rain" are one idea three times. Google's combinations need distinct lines or the ad only knows how to say one thing. Three ads in the same ad group should still be about the same product. They should not drift into a second collection because a writer got bored.

When a pin is justified

Leave headlines unpinned so the system can find combinations that earn the click. Pin a line only when showing it is a requirement: a legally required disclaimer you have decided to put in the ad, or an offer that would make the rest of the ad misleading if it did not appear. A pin is not how you force your favorite adjective into position one.

If you pin, the pinned line has to clear the character limit on its own, and you should accept that you have reduced the number of combinations. Most ecommerce ad groups do not need that trade.

Match the ad group, not the whole store

An ad group for a single model should not inherit headlines from the parent collection if those headlines name products this page does not show. An ad group for a problem or use case should still land on a page that answers that problem. If you cannot write three true headlines for the URL, the ad group is pointed at the wrong URL, or the page is not ready. Fix that before you write more copy. The checks in the landing page readiness audit are the same checks a writer needs.

How Kopa drafts the ads

In Kopa, Smart Campaigns writes three to four unpinned Responsive Search Ads per ad group from the store's own USPs, numbers, reviews, and the call to action on the landing page. The drafts stay editable until your team approves them.

What good looks like

  • Each ad group has three or four Responsive Search Ads, not one.
  • Headlines are distinct facts from the destination page.
  • Pins are rare and explained.
  • No headline names a product, discount, or competitor the page does not support.
  • The call to action matches the control on the page.
