Quality Score is the reason two Singapore businesses can bid exactly the same amount and pay wildly different prices for the same click. One pays S$2.20, the other pays S$6.80, for the identical keyword and the identical position. The difference is not budget or luck — it is relevance, and Google measures it with a 1-to-10 rating called Quality Score. Improving it is the single cheapest way to lower your Google Ads costs, because it lets you pay less for the same clicks without touching your bids. This guide explains, without the jargon, what Quality Score is, why it controls what you pay, and exactly how to raise it.
If you want the wider context of how the auction and bidding work first, our complete Google Ads guide for Singapore SMEs covers the fundamentals. This post goes deep on the one metric that quietly decides your cost-per-click.
What Quality Score actually is
Quality Score is Google’s 1-to-10 rating of how relevant and useful your ad and landing page are for a given keyword. You see it per keyword in your Search campaigns. A 10 means Google thinks your ad is highly relevant and your landing page genuinely answers the searcher; a 1 means it thinks you are showing an ad people do not want, pointed at a page that does not deliver.
It is built from three ingredients, each rated “Above average”, “Average” or “Below average”:
- Expected click-through rate (CTR) — how likely Google thinks people are to click your ad when it shows for this keyword, based on its and similar advertisers’ historical data.
- Ad relevance — how closely your ad copy matches the intent behind the keyword and the user’s search.
- Landing page experience — how relevant, useful, fast and mobile-friendly the page is that people land on after clicking.
Combine the three and Google produces the 1–10 score. Crucially, the three ingredients are not weighted equally. Analysis of the formula suggests expected CTR and landing page experience each carry roughly 39% of the weight — about 78% between them — while ad relevance contributes around 22%. In plain terms: how clickable your ad is and how good your landing page is matter far more than how neatly your keyword appears in the headline.
Why it matters: you pay less for more
Here is the part that turns Quality Score from a vanity metric into money. Google does not simply auction ad positions to the highest bidder. Your position is decided by Ad Rank, which is roughly your bid multiplied by your ad quality (plus expected impact from extensions and context). A high-quality ad can outrank a higher bid. And the price you pay is calculated to reward quality — so a strong Quality Score earns you better positions at a lower cost-per-click, while a weak one makes you pay a premium just to show up at all.
The size of that effect is large. Industry analysis puts it like this:
| Quality Score | Effect on cost-per-click |
|---|---|
| 1–3 (poor) | You can pay up to 400% more than the baseline |
| 5 (average) | The reference point — neither penalty nor discount |
| 7–8 (good) | A meaningful discount; ahead of most advertisers |
| 10 (excellent) | Up to a 50% discount on cost-per-click |
To put numbers on it for Singapore: if an “aircon servicing” keyword costs S$4 a click at an average Quality Score of 5, the same keyword could cost well over S$8 at a Quality Score of 2, and closer to S$2 at a Quality Score of 9 or 10. Same auction, same bid, less than half the price — purely because the ad and page are more relevant. That is why improving Quality Score directly improves what your Google Ads cost more reliably than any bidding trick.
What counts as a good Quality Score?
For context, WordStream’s analysis of more than 15,000 Google Ads accounts found the average Quality Score sits around 5 to 6 out of 10. Anything at 7 or above puts you ahead of the majority of advertisers in almost every industry. So you do not need a perfect 10 on every keyword — you need to be consistently above the average crowd you are bidding against. A few keywords stuck at 3 or 4 are where the money leaks, and those are the ones to fix first.
A note on “does Quality Score still matter in 2026?”
You may read that Quality Score is “just a diagnostic” and no longer used in the auction. That is half true and worth understanding. Google has said the visible 1–10 number you see in the interface is a diagnostic indicator — it is not literally the value plugged into the live auction. But the auction still uses expected CTR, ad relevance and landing page experience to decide Ad Rank and your cost — the very same three components that make up Quality Score. So the score is a thermometer, not the fever itself: improving the things it measures genuinely lowers your costs, even in today’s automation-heavy accounts. Ignore the debate about the number and focus on the three inputs.
How to improve your Quality Score
Because the three components are weighted differently, the order of effort matters. Spend your time where the leverage is highest.
1. Lift your landing page experience (high leverage)
Landing page experience carries roughly 39% of the weight and is where most Singapore SMEs lose points. Google wants the page to answer the search clearly, load fast, and work on mobile. Practical fixes:
- Match the page to the ad’s promise. If the ad says “aircon servicing from $X”, the page must lead with aircon servicing — not a generic homepage. Mismatched pages are the most common cause of a “Below average” landing page rating.
- Make it fast. Most Singapore searches are on mobile; a slow page tanks both Quality Score and conversions. Compress images, cut unnecessary scripts, and aim for a quick load on a phone.
- Make the action obvious. One clear call to action — call, WhatsApp, or a short form — above the fold. A page that is fast and relevant but hides the next step still wastes the click. Fixing the landing page also resolves most of the reasons Google Ads stop converting.
2. Raise your expected click-through rate (high leverage)
Expected CTR also carries roughly 39% of the weight. Google predicts how clickable your ad is from history, so the way to improve it is to write ads people actually click:
- Mirror the search in the headline. If someone searches “corporate video production Singapore”, an ad headline containing those words feels relevant and earns clicks.
- Lead with a clear, specific offer or benefit, not a vague slogan. Specifics (“Same-day quote”, “10-year warranty”) beat platitudes.
- Use every relevant ad extension — sitelinks, callouts, structured snippets, call and location. Extensions make the ad bigger and more useful, lifting CTR and Ad Rank.
- Pause the chronic non-clickers. Ads that consistently underperform drag the average down; replace them.
3. Tighten ad relevance (lower leverage, still worth it)
Ad relevance is about 22% of the weight, but it is easy to fix and underpins the other two:
- Group keywords into tight themes. Do not stuff 60 loosely related keywords into one ad group; the ad cannot be relevant to all of them. Small, tightly themed ad groups let each ad mirror its keywords closely.
- Use the keyword’s language in the ad. Reflecting the actual search terms in your headlines and descriptions is the simplest way to earn an “Above average” relevance rating.
- Mind your match types. Looser match types pull in searches your ad was not written for, hurting relevance — our guide to Google Ads match types explains how to keep your ads pointed at the right queries.
The recurring theme is relevance at every step: the keyword, the ad and the page should all be about the same thing. When they line up, Quality Score rises and your cost falls. Small relevance improvements usually cut cost-per-click more than raising bids ever will.
A worked Singapore example
A local renovation company we looked at was bidding aggressively on “home renovation Singapore” but paying around S$9 a click and barely breaking even. Their Quality Score on the term was 3. The problems were textbook: one giant ad group with 40 unrelated keywords, a single generic ad, and a landing page that was the company homepage — slow, and not specifically about renovation. We split the keywords into tight themed groups, wrote ads that mirrored each theme, and pointed each to a fast, matching landing page. Within six weeks the keyword’s Quality Score climbed to 7, and the cost-per-click fell to roughly S$5 — a 40-plus percent saving with no change to the bid. That is Quality Score doing its job: rewarding relevance with a lower price.
The knock-on effect mattered more than the headline saving. Because each click cost less, the same monthly budget bought noticeably more clicks; because the landing page now matched the ad, a larger share of those clicks turned into enquiries. Lower cost-per-click and higher conversion rate compound — the company ended up with roughly double the leads for the same spend. None of it came from clever bidding. It came from making the keyword, the ad and the page all about the same thing, which is the entire game with Quality Score.
Where to find your Quality Score
Quality Score is hidden by default, which is part of why so many advertisers ignore it. To see it, go to the Keywords view in a Search campaign, click the columns icon, and add the Quality Score column — along with the three component columns: “Exp. CTR”, “Ad relevance” and “Landing page exp.”. Those three diagnostic columns are where the real value sits, because they tell you which ingredient is dragging a keyword down. A keyword scoring 4 with “Below average” landing page experience needs a better page; the same 4 with “Below average” expected CTR needs a better ad. Always treat the components as your to-do list, not the headline number.
It is also worth adding the historical Quality Score columns when you review, so you can see whether your fixes are moving the score in the right direction over weeks rather than judging it day to day.
Quality Score vs Ad Strength — don’t confuse them
A common 2026 mix-up: people see “Ad Strength” (rated Poor to Excellent on responsive search ads) and assume it is the same as Quality Score. It is not, and conflating them leads to wasted effort. Ad Strength measures how well you have built a single responsive search ad — whether you have enough headlines and descriptions, enough variety, and relevant keywords in them. It is a creative-completeness checklist. Quality Score measures how relevant and useful your keyword, ad and landing page are to searchers, and it is what actually influences your cost and position.
You can have an “Excellent” Ad Strength and still a poor Quality Score if your landing page is weak or your keyword is a bad match for your offer. Both are worth improving, but if you have to choose, Quality Score and its three components are the ones tied to what you pay. Use Ad Strength to make sure each ad is fully built; use the Quality Score components to make sure the whole chain — keyword to ad to page — is relevant.
Quality Score and GST — the Singapore money picture
A quick reminder on what you actually pay. GST of 9% has applied to Google Ads spend since 1 January 2024, on both media and any agency fee, so the gross cost is higher than the click prices suggest. Lowering your Quality Score-driven CPC therefore saves you the click price and the GST on it. With typical Singapore CPCs running S$1.50 to S$6 for most sectors and up to S$8–S$11 for legal and B2B, a Quality Score improvement that shaves 30–40% off CPC is one of the highest-return hours you can spend on an account.
One grant clarification while we are on costs: ad spend and ongoing management are generally not claimable under PSG or similar grants, which fund pre-approved software rather than media budgets. SDM is a pre-approved PSG vendor for eligible solutions, but you apply for and manage any grant yourself.
Common Quality Score mistakes
- Raising bids to fix a low score — it costs more and fixes nothing durable.
- Cramming dozens of unrelated keywords into one ad group.
- Sending paid clicks to a generic homepage instead of a matching landing page.
- Ignoring page speed on mobile, where most Singapore traffic is.
- Running the same two tired ads for a year and never testing fresh ones.
- Skipping ad extensions, which lift both CTR and Ad Rank for free.
The bottom line
Quality Score is not a vanity metric — it is the dial that decides how much you pay for every click. It rewards one thing above all: relevance between the keyword, the ad and the landing page. Get those three aligned and Google literally charges you less, often dramatically so, for the same positions. For most Singapore SMEs, improving Quality Score is a faster route to lower costs and more leads than raising budgets ever is.

FAQ
What is Quality Score in Google Ads?
It is Google’s 1-to-10 rating of how relevant and useful your ad and landing page are for a keyword, built from three components: expected click-through rate, ad relevance and landing page experience. You see it per keyword in Search campaigns.
Why does Quality Score matter?
It directly affects your cost. A higher score wins better ad positions at a lower cost-per-click, while a low score makes you pay a premium — a poor keyword can cost up to 400% more per click than average, and an excellent one up to 50% less.
What is a good Quality Score?
The average across accounts is around 5 to 6 out of 10. A score of 7 or above puts you ahead of most advertisers. You do not need a perfect 10 everywhere — focus on lifting the keywords stuck at 3 or 4, where you are overpaying.
How do I improve my Quality Score?
Improve the landing page (match the ad, load fast, be mobile-friendly) and lift click-through rate (mirror the search, use extensions, write sharper ads) first, because those two carry most of the weight. Then tighten ad relevance with tight, themed ad groups.
Does raising my bid fix a low Quality Score?
No. Raising bids only makes each click more expensive without addressing the relevance problem. Improving the ad and landing page is the cheaper, more durable fix and lowers your cost-per-click instead of raising it.
Does Quality Score still matter in 2026?
Yes. Google calls the visible number a diagnostic, but the auction still uses expected CTR, ad relevance and landing page experience — the same three components — to set Ad Rank and your cost. Improving what Quality Score measures genuinely lowers what you pay.
