Google Ads for beginners: a small-business guide

By Jo van Vuuren — Fractional CMO

Google Ads is Google’s pay-per-click advertising system: you write an advert, choose which searches you want it to appear on, and pay only when someone clicks through to your website. For a small business it can be a fast way to get in front of people who are searching for exactly what you sell, but it only pays off if a few things are set up correctly first.

What is Google Ads, in plain terms?

When someone searches on Google, adverts can appear above or alongside the normal search results, marked with a small “Sponsored” label. You choose the words or phrases (called keywords) that trigger your advert, write the advert text, and set a budget for how much you are willing to spend. You are charged each time someone clicks, not for how many people simply see the advert, which is why it is often called PPC, pay-per-click.

How does the auction decide whose advert shows?

Every time someone searches, Google runs a quick auction between everyone bidding on that search term. It is not simply about who bids the most. Google also looks at how relevant and well-built your advert and landing page are, and rewards adverts that are likely to be useful to the person searching with a lower cost and a better position. A smaller business with a well-targeted, relevant advert can beat a bigger competitor’s bigger budget.

• Your bid: the most you are willing to pay per click
• How relevant your keywords, advert and page are to the search
• The expected usefulness of your advert to the person searching

How do keywords and intent work?

Keywords are the words or phrases that trigger your advert, and getting them right matters more than almost anything else in Google Ads. The key idea is intent: what the person typing that search actually wants. Someone searching “boiler repair near me” is ready to book; someone searching “how does a boiler work” is just researching. Aim your budget at the searches that show someone is ready to act, and be specific rather than broad, so your advert only appears for searches genuinely relevant to what you offer.

• Specific, intent-led phrases usually convert better than broad, general terms
• Use negative keywords to stop your advert showing for irrelevant searches
• Group similar keywords together so each advert stays relevant to the search

Why your landing page decides whether the click pays off

The page someone lands on after clicking your advert matters as much as the advert itself. If your advert promises “same-day boiler repair” and the click lands on your homepage with no obvious way to book, most visitors will simply leave. A good landing page matches what the advert promised, loads quickly, and makes the next step (calling, booking, buying) obvious. Without this, you are paying for clicks that lead nowhere, however good your advert is.

Alongside a good landing page, set up conversion tracking: a short piece of code that tells you when a click has turned into an enquiry, a booking or a sale. Without it, you only know how many people clicked, not whether any of them actually became customers, which makes it impossible to judge whether the campaign is worth the spend.

What mistakes do beginners usually make?

Most beginner mistakes come down to spending money before the basics are in place. Getting these right before you launch saves budget that would otherwise be wasted on clicks that were never going to convert.

• Bidding on broad, generic terms that attract browsers rather than buyers
• Sending clicks to a generic homepage instead of a page built for that advert
• Not setting up conversion tracking, so you cannot see which clicks actually turned into enquiries or sales
• Leaving a campaign running unchecked instead of reviewing which keywords are working
