Google Ads Quality Score: How to Improve It and Cut CPC

If your cost per click keeps rising while competitors seem to pay less, Google Ads quality score is the first place to look. It is the diagnostic that tells you whether your keywords, ads and landing pages fit what people are actually searching for.

This guide explains what the score measures, what it does and does not control, and the specific fixes that lift each component. It is written for Indian advertisers who run search campaigns for services, D2C stores or lead generation, and who want to lower cost per lead without simply raising bids.

What is Google Ads Quality Score?

Quality Score is a 1-10 diagnostic, shown at keyword level, that compares your ad quality with other advertisers. Google's own help page says it is not a key performance indicator and not an input in the ad auction, but a tool for spotting where ads, keywords or landing pages could improve.

That wording matters. Many accounts spend weeks trying to move every keyword to 10/10 and report the average as a goal. Google says the score should not be optimised or aggregated with the rest of your data. Use it the way a mechanic uses a warning light: it points to a problem area, and you fix the cause.

What are the three components of Quality Score?

The score combines three components, each rated Above average, Average or Below average against advertisers who showed ads for the same searches over the previous 90 days.

You can add these columns to your keyword report from the columns menu in Google Ads: Quality Score, Landing Page Exp., Exp. CTR and Ad Relevance. Sort by impressions or spend so you fix expensive keywords first, not obscure ones.

Does Quality Score really lower your CPC?

Quality Score does not set your CPC directly, but the quality signals behind it influence Ad Rank, and Ad Rank influences what you pay. Google explains that Ad Rank combines your bid, the quality of your ad and landing page, Ad Rank thresholds, the context of the search and the expected impact of assets and formats.

Two consequences follow from Google's Ad Rank explanation:

• Thresholds are stricter for low-quality ads. Google's Ad Rank thresholds documentation says lower quality ads face higher thresholds, which can make a click expensive even when few competitors are present.
• Relevance can beat a bigger bid. Google states that even if competitors bid more, you can win a higher position at a lower price with highly relevant keywords and ads.

So raising bids is not the only lever, and it is rarely the cheapest. Our Google Ads cost guide for India shows typical CPC ranges; quality work is how you try to land at the lower end of your category's range. It does not guarantee a particular CPC, because competition and the search itself also matter.

How do you improve each Quality Score component?

You improve Quality Score by finding the Below average component for your highest-spend keywords and fixing that specific cause. The table below pairs each component with changes that usually help.

Google's guidance on landing pages is direct: give people what they are looking for and keep messaging consistent from ad to page. If the keyword is "discount shoes" and the ad promises 20% off, the page should show discounted shoes. For Indian audiences, also check how the page behaves on mid-range Android phones and 4G connections, because that is where many clicks arrive.

How do you audit Quality Score step by step?

A short, repeatable audit beats a one-off clean-up. Run this routine monthly, or weekly on large accounts.

1. Add the columns. In the keyword view, add Quality Score and the three component columns.
2. Filter by spend. Sort by cost and look only at keywords that account for most of the budget.
3. Mark the Below average component. Note whether it is expected CTR, ad relevance or landing page experience.
4. Check the search terms report. Confirm that the queries triggering ads match the ad group theme, and add negatives for the rest.
5. Rewrite ads or regroup keywords. Fix ad relevance and CTR issues first because they are quick to change.
6. Fix the destination. Brief a dedicated page when a homepage is the landing page, using our landing page best practices.
7. Wait for data. Give changes enough impressions before judging, and change one thing at a time where you can.
8. Compare conversions. Judge the result by cost per lead and lead quality, not by the score.

Step 4 deserves emphasis. A keyword can look poor simply because it is matching searches your ad never addresses, so the cure is cleaner intent, not cleverer copy.

Which mistakes keep Quality Score low?

The same few mistakes appear in most accounts we review, and they are all fixable:

• One ad group for everything. Mixing "AC repair", "AC installation" and "AC service" under one ad makes every ad slightly irrelevant.
• Homepage as the destination. The visitor has to hunt for the offer, which hurts landing page experience and conversions.
• Promising what the page does not say. If the ad mentions free consultation, the page should show it above the fold.
• Ignoring mobile. Google takes the user's device into account when it calculates ad quality, so a poor mobile page lowers quality even if desktop looks fine.
• Chasing the number. Pausing useful low-volume keywords just to raise an average removes leads without helping the business.
• Changing too much at once. You cannot tell which change helped, and re-evaluation takes time.

For pages that rank organically and run paid traffic, the speed work in our technical SEO checklist helps both channels.

How Arham Technology approaches Google Ads quality

Arham Technology treats ad quality as part of account structure rather than a separate task. Our PPC and Google Ads management service follows this sequence:

1. Account forensics. We review spend by keyword, the three quality components, search terms and tracking before changing live bids.
2. Intent architecture. Campaigns and ad groups are rebuilt around how buyers search, so each ad can mirror its keywords.
3. Message-matched destinations. We write briefs for purpose-built pages, or build them through our landing page development service when the page is limiting results.
4. Tracking truth. Conversions are verified in GTM and GA4 so Smart Bidding learns from real enquiries.
5. Review and prune. Negative keywords and ad variations are updated from search term reviews, with lead quality checked against your sales team's feedback.

We will tell you honestly when a budget is too small to learn from, and we do not promise specific scores, rankings or returns.

What should you do next?

Open your keyword report, add the three component columns and list the five keywords with the highest spend. For each, write down the weakest component and one change you can make this week. Fix the ad group structure or landing page for those keywords before touching bids.
