Google Ads quality score landing page: the cause
Your score dropped, and the account only shows a rating for each part. Mimiq sends simulated visitors who searched that keyword to your page and shows the step where each one stops.
Why did my Google Ads quality score drop, and is the landing page the cause?
The score is built from three parts: expected click-through rate, ad relevance, and landing page experience. Each part gets its own rating for each keyword, so you can see which one is below average. Only landing page experience comes from the page itself, and it reflects how relevant the page is to the keyword and how well it works for the visitor. Mimiq sends simulated visitors who searched that keyword through the page and shows where they stop.
What this looks like in a report
“I searched for team scheduling software, and this hero talks about workplace productivity for everyone. Where is the scheduler? I came for shifts, not productivity. I'll try the next result.”
The fix. Put 'team scheduling software' in the headline and add a screenshot of the shift calendar above the fold. Point the keyword's ad group at this page only, not the homepage.

The page is one of three parts, and the easiest to blame
Google rates each keyword on three parts. Expected click-through rate is how often people click the ad when it shows. Ad relevance is how closely the ad matches the keyword. Landing page experience is how well the page matches the keyword and how it works once someone arrives. Teams often blame the page for a score the ad copy caused, because the page is the part they can edit. Ratings also lag behind changes. A new keyword may show no rating at all until it has served enough impressions, and a page fix can take a while to appear in the account.
- Keyword ratings: which part is below average, the page, the ad copy or the ad group?
- Ad group keywords: does each keyword appear in a headline or the first line of the ad?
- Final URL history: did the page change recently, and does it still open the same product?
- Phone first screen: does the keyword's product noun appear above the fold, not in a footer?
How it works
- 01
Read which part is below average
Open the keyword view and find the expected click-through rate, ad relevance and landing page experience ratings. If only the landing page rating is below average, the page is the cause. If expected click-through rate is the weak one, change the ad copy before you touch the page.
- 02
Put the keyword's words on the first screen
Use the product words the searcher typed in the headline and the line under it, in the same order. Keep the Final URL the same, so you compare one page before and after the change.
- 03
Send a searcher through before the rating moves
Ratings update slowly, so waiting for the score tells you little about the page. Run a simulated visitor who searched the keyword through the fixed page and read the step where they stop.
The keyword view names the part that is failing
Open the keyword view and read the three ratings before you change anything. Each one points to a different owner: the ad copy, the ad group's keyword list, or the page. A score can fall for a reason that has nothing to do with the page, such as a weaker headline added to the group. Note which rating dropped and the date it changed, then compare that date with your last edit to the ad and to the page. If the dates line up with a page edit, look at that edit first. If they do not, the page is probably not the cause, and the next change belongs on the ad.
One landing page for a whole ad group weakens every keyword
Many accounts send ten keywords with different meanings to one homepage. The landing page rating is judged keyword by keyword, and a page that serves a broad mix of words can match some of them and fail the rest. Split the group by theme, then give each group a page whose first screen uses that group's words. Keep the old page for its own keywords, so the change does not move traffic you were already getting.
A page edit can remove the words a rating depended on
A redesign often removes a keyword's words without anyone deciding to. The old headline said invoice software, the new one says Get paid faster, and the ad group still searches for invoice software. Compare the old and new first screens word by word against the keyword. If the product noun disappeared, that is your cause, and restoring the noun is cheaper than rebuilding the ad group. Confirm the restored page with one visitor who searched the keyword before you wait for the rating to recover.
What you get with Mimiq
- 01
Run it by hand, or on every pull request
Paste a link and a task in the app and watch the visitors work. Or run them on every preview deploy: the GitHub Action comments on the pull request, any other CI can call the MCP endpoint, and your coding agent can run it too.
- 02
Bugs and usability problems in one report
The browser records errors and failed or slow requests on the step they happened. The visitors say where the wording or the steps confused them, and where they left.
- 03
Visitors that behave like your audience
Each visitor is a different profile with a reason to be there, matched to who the page is for, described by you, or built from your own customers.
- 04
A prompt to fix each problem
Every problem comes with a fix to paste into Cursor, Claude Code, Lovable or any coding agent, and one prompt hands over the top problems at once. Then send the same visitors through again.
- 05
Follow every visitor
See each visitor's whole path, step by step with screenshots, and what it was thinking at every step. Ask any visitor a question.
The browser records relevant JavaScript errors and failed or slow app requests encountered during the run, attached to the step where they occurred. The visitors are simulated: they find problems, they do not predict how many real people will convert.
A page edit next month can drop a keyword that worked this month
Pages change for reasons that have nothing to do with ads, such as a new banner, a menu change or a redesigned hero. Each change can move the words a keyword depends on, and the rating shows the damage late. Run the same searcher through the page after each release and compare where they stop. Test any page behind a login with a test account, and check it again before the next keyword set goes live.

Questions
Does a higher quality score lower what I pay per click?
Quality score is one input to ad rank, and ad rank affects what you pay for a click, so a better score can lower the cost. Competition for the same keyword moves the price too, and so do your bids. Mimiq does not read your bids, costs or account settings, so check the cost change in the account after the page works.
Will fixing the page raise the score right away?
Not always. The rating depends on how the keyword has performed, so it can lag behind a fix. Send a searcher through the fixed page to see whether it works now, then check the rating in the account on a later day. A simulated visitor shows where the page loses a searcher. It does not predict the next score.
Should I pause keywords with a low score?
That is a budget decision, and a test cannot make it for you. A low score on a keyword whose page works may point to the ad copy or a broad match rather than the page. Compare the three parts first, then decide. The simulated visitor can show whether the page delivers the keyword, but not whether the keyword is worth paying for.
Can a simulated visitor see my score?
No. It has no access to your account, your keyword list or the rating Google shows for each part. What it can do is read the page the way someone who typed the keyword reads it, and report the step where they stop, with the screenshot and their reason.
Does the test check mobile too?
Yes, a visitor can run on a phone or a laptop browser at a public address. If most of your clicks come from phones, run the phone path first, before you change anything else. The run uses a standard browser, so a page that needs an installed app stops the visitor at that step.
