Google Ads Quality Score Is Low: What Actually Affects It?
A low Quality Score tells you Google thinks your ad, keyword and landing page are not well aligned with the search. It is a diagnostic signal, not a performance metric on its own. The three components tell you where the mismatch is so you can fix the real problem instead of chasing the score.

What Quality Score measures
Quality Score has three components: expected clickthrough rate, ad relevance and landing page experience. Each is rated separately. A low score means one or more of these is weak. The score is a summary of how well your setup matches the search, not a goal in itself.
What to check first
- Check the component ratings, not just the overall score.
- Identify which component is weak.
- Review the keyword intent.
- Review the ad copy for relevance.
- Review the landing page for alignment.
Expected CTR
Expected CTR predicts whether your ad will get clicked. If it is weak, the ad is not compelling or relevant enough for the search. Improve headlines, match the offer to the search and make the ad stand out. A weak expected CTR often points to ad copy or keyword intent problems.
Ad relevance
Ad relevance measures how closely your ad matches the keyword. If it is weak, the ad does not reflect what the searcher typed. Group keywords tightly so each ad matches one intent, and write headlines that include the search intent. Relevance improves when the ad answers the search.
Landing page experience
Landing page experience measures how useful and relevant your page is. If it is weak, the page does not match the ad or is hard to use. Align the page headline with the ad, make the offer clear, improve load speed and ensure mobile usability. The page should deliver what the ad promised.
Keyword intent and historical performance
The keyword intent drives the score. A keyword that attracts the wrong searches will have low relevance and low CTR. Historical performance also matters: a new keyword has little data, so the score may be low until it builds history. Do not panic over a low score on a new keyword.
Quality Score is not the only metric
A high Quality Score does not guarantee good results and a low one does not guarantee bad results. Judge the campaign by conversions, cost per lead and lead quality, not the score alone. Use the score as a diagnostic to find weak spots, then check whether those weak spots actually hurt performance.
How to improve it
- 1.Check which component is weak.
- 2.If ad relevance is weak, tighten ad groups and rewrite ads.
- 3.If expected CTR is weak, improve headlines and offers.
- 4.If landing page is weak, align the page with the ad and improve usability.
- 5.Monitor conversions and lead quality, not just the score.
Frequently Asked Questions
Does a low Quality Score mean my ads will not show?
Not necessarily. A low score can reduce Ad Rank and raise CPC, but ads can still show. Focus on the three components to find the real mismatch and judge performance by conversions.
Can I have a low Quality Score but good performance?
Yes. Quality Score is a diagnostic signal, not a performance metric. Some keywords perform well despite a low score. Use the score to find weak spots but judge the campaign by real results.
