Ad Quality Score Explained: How to Pay Less Per Click
What 'quality score' and ad relevance really mean, why they decide how much you pay, and seven practical ways to improve them so your ads cost less.
Two Zimbabwean businesses can run almost the same advert to the same audience and pay wildly different prices for a single click — one pays a few cents, the other several times more. The difference is rarely the budget. It is quality and relevance, and it quietly decides how much every click costs you.
What is quality score (and ad relevance)?
Every ad platform tries to show people ads they actually want to see. To do that it scores your ad on how relevant and useful it is likely to be — and it rewards good ads with cheaper clicks and better placement.
Google Ads calls this Quality Score, rated from 1 to 10. It is built from three things: your expected click-through rate (how likely people are to click), ad relevance (how closely your ad matches what the person searched for), and landing page experience (how good and relevant the page is that they land on).
Facebook and Instagram (Meta) use ad relevance diagnostics instead of a single number. They rate your ad on three rankings: quality ranking, engagement rate ranking, and conversion rate ranking, each shown as below average, average or above average. The idea is identical to Google's: the platform rewards ads people find relevant and useful with lower costs and stronger reach.
Why it matters for your money
Relevance is the lever that decides what you pay. A high-relevance ad wins the auction more cheaply, so you get a lower cost per click and more reach for the same budget — your $5 stretches to hundreds more people. A low-relevance ad does the opposite: the platform either charges you a premium to show it, or barely shows it at all. In practice that means you overpay for every order, or your advert quietly stops delivering while your budget sits unspent. Improving relevance is often the cheapest way to get more sales, because you are not adding money — you are just wasting less of it.
7 ways to improve your quality/relevance score
- Match the ad to the right audience. Tight targeting beats a big vague audience. When you show a school-shoes advert to parents in Harare rather than to everyone, more people find it relevant, engagement rises, and your score climbs.
- Write copy that speaks to that audience's need. Talk directly to the person you are targeting and the problem you solve for them. Generic wording like "great products, best prices" reads as noise; a specific promise earns the click.
- Use a strong, native-looking image or short video. Clear, well-lit creative that looks like it belongs in the feed stops the scroll. Stiff, overly designed or blurry visuals get ignored, and low engagement drags your ranking down.
- Make a clear, single offer and call to action. One offer and one action — "Shop now", "Order today" — always outperforms an advert crammed with five messages. Confusion kills click-through rate, and click-through rate feeds your score.
- Send clicks to a fast, relevant landing page. Point people to your shop page showing the exact product and price from the ad — not a slow homepage or a generic catalogue. This is the biggest single lever on your score. A fast, product-specific Shop263 storefront page matches the ad and loads quickly, which is exactly what the platforms reward.
- Keep it fresh. Ads fatigue as the same people see them repeatedly, engagement falls, and costs creep up. Refresh your creative and copy before that happens rather than after the numbers collapse.
- Avoid engagement bait and misleading claims. "Tag five friends", fake urgency, or promises the product cannot keep will get your ad penalised or rejected. Platforms actively push these down, so honesty is also the cheaper route.

Frequently asked questions
What is a good quality score?
On Google Ads, a Quality Score of 7 to 10 out of 10 is strong, 5 to 6 is average, and below 5 usually means you are overpaying. On Meta there is no single number — instead you want your ad relevance diagnostics to read as average or above average across quality, engagement and conversion ranking. Anything marked below average is a signal to fix the ad, the audience or the landing page.
Does my website or shop page affect my ad quality score?
Yes, a great deal. Landing page experience is one of the three parts of Google Quality Score, and Meta judges the whole journey from click to purchase. If your page loads slowly, does not match the ad, or is hard to use on a phone, your score drops and your cost per click rises. Sending clicks to a fast, product-specific page like a Shop263 storefront listing is one of the strongest moves you can make.
Why is my cost per click so high?
High cost per click almost always comes down to low relevance. If your ad does not match your audience, the creative is tired, or the landing page is slow or generic, the platform charges you more and shows you less. Tighten your targeting, refresh the ad, and point clicks to a fast page that matches the offer — the cost usually comes down without raising your budget.
