The short answer
Quality Score is Google’s 1-10 diagnostic rating of how relevant and useful your ad and landing page are for the keywords you’re bidding on, and it directly affects what you pay per click. Google Ads Help defines it as being based on three components: expected clickthrough rate, ad relevance, and landing page experience — a low score on any one of these can raise your cost per click even when your bid stays the same.
A higher Quality Score doesn’t guarantee a lower price on its own, but it consistently improves the efficiency of a given budget, since Google rewards ads and landing pages that match what searchers are actually looking for.
Quick-reference table
| Component | What It Measures | Quick Fix If It’s Weak |
|---|---|---|
| Expected clickthrough rate | Likelihood searchers click your ad for that keyword | Tighten keyword-to-ad group match; write ad copy that speaks directly to the search term |
| Ad relevance | How closely your ad copy matches the intent of the keyword | Use smaller, tightly themed ad groups instead of broad, mixed keyword lists |
| Landing page experience | How relevant and useful the destination page is to the click | Match the landing page headline and offer to the specific ad, not a general homepage |
| Historical account performance | Past performance across the account, factored in over time | Pause consistently underperforming keywords rather than letting them drag the account average down |
Expected clickthrough rate
What it means. This measures how likely searchers are to click your ad when it shows for a given keyword, compared to how other ads perform for similar searches. It’s a comparative, keyword-level prediction — not your literal historical CTR across the whole account.
Common causes of a low score here:
- ✓ Ad copy that’s generic enough to apply to almost any business in the category
- ✓ Keywords in an ad group with wildly different search intent grouped together
- ✓ Ad extensions (sitelinks, callouts) that are outdated, missing, or irrelevant to the offer
- ✓ Competing directly on branded terms owned by a much larger, more recognized competitor
What to do:
- ✓ Write ad copy that speaks directly to the specific keyword’s intent, not a generic value proposition
- ✓ Break large, mixed ad groups into smaller, tightly themed groups organized by real search intent
- ✓ Keep ad extensions current and directly relevant to what’s being advertised
- ✓ Test multiple headline variations within each ad group rather than running one static ad indefinitely
Ad relevance
What it means. This measures how closely the actual content of your ad matches what someone searching a specific keyword is looking for. It’s a check on message match at the keyword level, distinct from whether people click.
Common causes:
- ✓ One ad running across many keywords that don’t share the same core intent
- ✓ Ad copy written around the business generally rather than the specific product or service being searched
- ✓ Keywords added to an existing ad group because they’re “related enough,” rather than genuinely matching
- ✓ Outdated ad copy that no longer reflects the current offer, pricing, or service list
What to do:
- ✓ Group keywords so every keyword in an ad group could reasonably use the exact same headline
- ✓ Include the specific keyword phrase (or a close natural variant) in the ad headline itself where it fits naturally
- ✓ Regularly review and retire keywords that no longer match the ad group’s actual theme
- ✓ Rewrite ad copy whenever the underlying offer or service list changes, rather than leaving old ads running
Landing page experience
What it means. Google defines this as how relevant and useful your landing page is to people who click your ad — it accounts for message match, page load performance, mobile usability, and whether the page delivers on what the ad promised.
Common causes:
- ✓ Sending traffic to a general homepage instead of a page built around the specific ad’s offer
- ✓ Slow page load speed, particularly on mobile, where most paid traffic arrives
- ✓ A page that requires extra clicks or scrolling to find the offer promised in the ad
- ✓ Landing pages that haven’t been updated to match a current promotion or ad copy change
What to do:
- ✓ Build a dedicated landing page for each distinct offer or ad group rather than reusing one general page
- ✓ Confirm the headline and core offer on the page match the ad word-for-word where possible
- ✓ Test load speed specifically on mobile devices, since that’s where most paid search traffic lands
- ✓ Review our landing page optimization guidance for the specific, checkable fixes that move this component
When to bring in help. If Quality Scores are consistently low across most keywords despite ad copy changes, the landing page is usually the underlying issue — a structural problem that ad copy edits alone can’t fix.

Why Quality Score affects what you actually pay
What it means. Google Ads uses an auction system where ad rank combines your bid with Quality Score and other factors — a higher Quality Score can let an advertiser pay less per click than a competitor with a lower score, even at a similar bid.
What to do:
- ✓ Treat Quality Score as a diagnostic tool for finding weak spots, not a metric to chase for its own sake
- ✓ Focus improvement effort on the keywords driving the most spend, not every keyword in the account equally
- ✓ Recheck Quality Score after any significant change to ad copy, landing pages, or ad group structure
- ✓ Remember that Quality Score is directional and keyword-specific — a “6” on one keyword and a “6” on another don’t necessarily mean identical underlying problems
FAQ
What is a good Quality Score?
Google Ads Quality Score ranges from 1 to 10, and generally 7 or higher is considered solid. There’s no universal “perfect” score to chase — the more useful practice is watching for keywords scoring notably lower than the rest of the account and fixing the specific component pulling them down.
Does Quality Score directly determine ad rank?
Not entirely on its own. Quality Score is one input into Google’s ad rank calculation alongside your bid and other auction-time factors, but a stronger Quality Score generally means paying less to achieve the same ad position.
Can a new ad account have a Quality Score right away?
New keywords typically show Quality Score once they’ve generated enough impressions and clicks for Google to evaluate the three components. Very new or low-volume keywords may show no score yet.
Does landing page speed alone fix a low Quality Score?
Not by itself, but it’s one of several factors within landing page experience. Message match and mobile usability matter alongside speed — improving all three together tends to move the score more than fixing just one.
Should every keyword in an account have the same Quality Score?
No, and that’s normal. Quality Score is evaluated per keyword, since different keywords can have different levels of ad relevance and landing page match even within the same campaign.
Improving Quality Score across an account
Quality Score improvements compound — a better landing page and tighter ad copy work together, and fixing one component often makes the others easier to improve too. SDB4U’s landing page optimization and Google Ads management services work through all three components systematically rather than guessing which one is weak.
