If your search campaign’s click-through rate is falling, ad fatigue is almost certainly not the reason. Fatigue needs the same person to see the same ad repeatedly, and search does not work that way, a homeowner looks for a plumber once every few years.
Why search ads do not really fatigue
An ad fatigues when the audience is fixed and the impressions keep landing on it. That describes social feeds and display banners, where the platform shows your ad to the same people day after day until they stop noticing.
Search is the opposite arrangement. You appear when somebody types the query, and the population typing it turns over constantly. Most people who see your ad this month have never seen it before, and most will not see it again for years. There is no accumulating exposure to wear out.
The advice that follows from the fatigue diagnosis reflects this. Frequency caps, the standard fix, are not a setting on the search network at all. They exist for display, video and demand generation campaigns, which is a fair indication of where the problem actually lives.
What a falling click-through rate usually means instead
The symptom is real even when the diagnosis is wrong. Work through these before touching the creative:
- A competitor entered the auction. The most common cause by some distance. Another firm started bidding on your terms, took the position above you, and your rate fell without anything of yours changing.
- Your average position slipped. Bids held steady while others rose, or quality signals drifted. Same ad, lower slot, fewer clicks.
- Match types broadened. Whether you changed them or the platform did, your ad is now showing on looser queries. Impressions rise, relevance falls, and the rate drops arithmetically without any single query performing worse.
- The season turned. The people searching in November want something different from the ones searching in July. An ad written for the summer question reads as a mismatch in the autumn.
- Something changed on the page. Not a rate problem directly, but it moves conversions, and conversion falls are often reported as fatigue.
Each of these has a different fix, and none of them is a new headline. Check the search terms report and the auction insights before rewriting anything.
Where fatigue is genuinely your problem
Contractors do run campaigns where the mechanism applies, and there it matters.
Retargeting. This is the real culprit. A thirty-day membership window means somebody who visited once is followed around the internet for a month. They notice, and they resent it. Shorten the window: a week or two is plenty for most home services, cap impressions, and exclude people who already converted, which many accounts never set up.
Paid social. A local audience is small and finite. Run the same creative into a town of forty thousand for two months and the same feeds see it repeatedly. Here, refreshing the creative is the correct answer.
Display and video. Same mechanism, same fix.
The distinguishing question is simple: is the platform choosing to show this to a fixed audience, or is a person choosing to search? Fatigue only applies to the first.
What to refresh, and when
On search, update creative when something has actually changed: a new service, a price, a season, an offer, a competitor claim worth answering, rather than on a schedule. Rotating headlines to stay fresh gives up whatever performance history the existing ones had, and buys nothing back.
On social and retargeting, a rotation is worth keeping. Several genuinely different pieces of creative in the mix, changed each season, will hold up better than variations on one theme.
Frequently asked questions
How often should I refresh my search ads?
When something changes, not on a calendar. Search audiences turn over continuously, so an ad does not go stale from exposure the way a social ad does.
My click-through rate dropped. What should I check first?
Auction insights, to see whether a competitor arrived, and the search terms report, to see whether you are showing on looser queries than before. Between them they explain most sudden falls.
Can I set a frequency cap on Google Search ads?
No. Frequency capping is available for display, video and demand generation campaigns, not the search network, which tells you something about where fatigue actually occurs.
How long should my retargeting window be?
Shorter than most accounts have it. A week or two suits most home services; thirty days follows people long after the decision was made, and is where contractors generate genuine ad fatigue.
Where to start
Open auction insights for the campaign you think is fatigued. If a competitor’s impression share rose as your click-through rate fell, you have your answer, and no amount of new creative addresses it.
