Why your Google Ads are not converting (and how to fix it)

Google Ads that get clicks but no conversions are not a traffic problem. They are a structural problem. The three most common causes are broad match keywords with no negative keyword list, landing pages that do not match the ad promise, and conversion tracking that is not set up correctly. Fix these three things and most non-converting SA campaigns start performing.

This post is for South African founders and marketers who are spending money on Google Ads and not seeing leads, calls, or sales in return. The issues below are the ones that appear in almost every SA Google Ads audit we run.

Why do Google Ads get clicks but no conversions in South Africa?

The most common reason is keyword mismatch. Broad match keywords without a negative keyword list mean your ads show for searches that have nothing to do with your product. A Cape Town plumber running broad match on the keyword 'plumber' will also show for 'plumber salary Cape Town', 'plumber course online', and 'DIY plumbing'. These clicks cost R10 to R50 each and produce zero leads.

The second most common reason is a landing page that does not match the ad. If your ad promises a free quote in 24 hours and your landing page is a generic homepage with no visible quote request form, visitors leave immediately. Google calls this the landing page experience and it affects both your conversion rate and your Quality Score, which directly affects your cost per click.

What is a Google Ads Quality Score and why does it matter for SA businesses?

Quality Score is a 1 to 10 rating Google assigns to each keyword based on expected click-through rate, ad relevance to the keyword, and landing page experience. A Quality Score of 8 can achieve the same ad position as a competitor with Quality Score 4 while paying 40% to 50% less per click. For South African businesses where Google Ads CPC ranges from R10 to R200 depending on industry, improving Quality Score is one of the highest-leverage actions you can take.

Poor landing page experience is the most common Quality Score killer in SA accounts. A landing page that is slow on mobile, does not contain the keyword the visitor searched for, or has no clear call to action will score badly and increase your costs across the entire campaign.

What negative keywords should South African businesses add immediately?

Every SA Google Ads account should have negative keywords blocking job searches, competitor comparisons that are not relevant, and free or DIY variants. If you are a service business, add 'jobs', 'vacancy', 'salary', 'course', 'training', and 'DIY' as negative keywords immediately. These are searches from people who will never hire you and every click from them is wasted spend.

Review your Search Terms report weekly. This report shows the actual search queries that triggered your ads. Any query that is irrelevant becomes a negative keyword. Google's own recommendation is to review search terms after the first 48 hours of a new campaign and again weekly. Most SA business owners have never looked at this report.

What is wrong with running Google Ads campaigns without conversion tracking?

Without conversion tracking, you are spending money with no way to know if any of it is working. You can see clicks and impressions but you cannot see whether those clicks led to phone calls, form submissions, or purchases. Google's bidding algorithms also cannot optimise for conversions when there is no conversion data to learn from. They default to maximising clicks, which means maximum spend with no filter for quality.

Set up conversion tracking in Google Ads for every action that has business value: phone calls from ads, form submissions on your site, purchases, and chat initiations. Link your Google Ads account to GA4. Without these signals, you are flying without instruments.

How much should a South African business spend on Google Ads?

For a local service business, a starting budget of R2,000 to R5,000 per month gives enough data to make meaningful decisions after two to four weeks. Most SA service industries see CPC between R15 and R100 per click depending on competition. Legal, insurance, and financial services pay the highest CPCs, often R50 to R200. Trades, home services, and hospitality are typically R10 to R50 per click.

The minimum viable budget is determined by how many clicks you need to see at least five to ten conversions per month. If you have a 3% conversion rate and your CPC is R40, you need R1,300 in spend to get one conversion. At that rate, a R2,000 budget gives you roughly one or two leads per month, which is not enough to test properly. Scale your budget to where you can generate at least ten leads per month before drawing conclusions.

Frequently asked questions

What is the average Google Ads cost per click in South Africa?

Google Ads CPC in South Africa ranges from R3 for low-competition retail keywords to R150 or more for competitive service industries like legal and finance. Most SA service businesses pay between R15 and R80 per click. The exact CPC depends on your Quality Score, your bid strategy, and your competition level. Improving your Quality Score from 5 to 8 can reduce your CPC by 30% to 50% for the same keyword.

Should I use Broad Match or Exact Match for Google Ads in South Africa?

For most SA businesses starting with Google Ads, use Phrase Match or Exact Match for your core keywords and build a negative keyword list actively. Broad Match gives Google maximum latitude to show your ads for loosely related searches, which generates clicks but not necessarily relevant traffic. As your campaign matures and you have sufficient conversion data, you can test Broad Match with a well-developed negative keyword list and Smart Bidding.

How do I know if my Google Ads landing page is good enough?

The landing page must match the promise of the ad, load in under three seconds on mobile, have a single clear CTA above the fold, and contain the primary keyword in the headline. Test it yourself by clicking your own ad on a mobile device. If anything feels unclear, slow, or frustrating, it is costing you conversions. Google's PageSpeed Insights and the landing page experience rating in your Quality Score report both give objective feedback.
