Google processes billions of searches every day, and many of those searchers are ready to buy. Google Ads lets your business appear at the top of search results for the exact searches that matter to you, and you only pay when someone clicks. This beginner's guide explains how Google Ads works and how to set up your first campaign without wasting money.

What Is Google Ads?

Google Ads is Google's advertising platform. You can show ads on:

  • Google Search results (text ads),
  • YouTube (video ads),
  • the Display Network (banner ads on millions of websites and apps),
  • Google Maps, Shopping results and more.

Most beginners start with Search campaigns, because they target people actively looking for products or services.

How Google Ads Works

Google Ads uses an auction. When someone searches, Google considers advertisers bidding on relevant keywords and decides which ads to show based on:

  • your bid — the maximum you're willing to pay per click,
  • Quality Score — how relevant and useful your ad and landing page are,
  • ad extensions and format — extra information like phone numbers and links.

This means a smaller business with highly relevant ads can outrank a bigger spender with poor ads.

Before You Start

Make sure you have:

  1. A clear goal: calls, form enquiries, WhatsApp chats, sales or store visits.
  2. A good landing page: fast, mobile-friendly and focused on the offer in your ad.
  3. A budget you're comfortable testing for several weeks.
  4. A way to track conversions, such as Google Analytics or Google Ads conversion tracking.

Step 1: Create Your Account and Campaign

  1. Sign up at ads.google.com with a Google account.
  2. Switch to Expert mode if you want more control (optional for beginners).
  3. Choose your goal and select Search as the campaign type.
  4. Set your locations (for example, only Lagos or only Nigeria) and languages.

Step 2: Set Your Budget and Bidding

  • Daily budget: start small and increase as you see results.
  • Bidding strategy: beginners often start with "Maximise clicks" or "Maximise conversions" once conversion tracking is set up.

Monitor spend daily during the first weeks.

Step 3: Choose Keywords Carefully

Keywords decide when your ads appear:

  • Focus on buying-intent keywords: "emergency plumber Abuja", "buy office chairs online", "wedding photographer Lekki".
  • Group closely related keywords into ad groups.
  • Use keyword match types:
    • Broad match: reaches related searches (use with care and conversion tracking).
    • Phrase match: searches that include your phrase's meaning.
    • Exact match: searches with the same meaning as your keyword.
  • Add negative keywords to exclude irrelevant searches, such as "free", "jobs" or "DIY" if they don't fit.

Step 4: Write Compelling Ads

Responsive search ads let you add multiple headlines and descriptions, which Google combines and tests. Tips:

  • include the keyword or its meaning in headlines,
  • highlight benefits and differentiators (same-day delivery, free consultation),
  • mention prices or offers if competitive,
  • add a clear call to action ("Book today", "Get a free quote"),
  • ensure the ad matches your landing page.

Step 5: Add Assets (Extensions)

Assets make ads larger and more useful:

  • sitelinks to specific pages,
  • call assets with your phone number,
  • location assets linked to your Google Business Profile,
  • callouts like "Free delivery" or "24/7 support",
  • structured snippets listing services or products.

Step 6: Set Up Conversion Tracking

Without tracking, you can't tell which keywords bring customers. Track form submissions, calls, WhatsApp clicks and purchases. Connect Google Ads with Google Analytics — see our Google Analytics guide.

Step 7: Launch, Monitor and Optimise

In the first weeks:

  • check the search terms report to see real searches triggering your ads, and add negatives,
  • pause keywords that spend without converting,
  • increase bids or budget on profitable keywords,
  • test new headlines and landing page improvements,
  • review results weekly.

Improving your landing page often boosts results more than changing bids. Our guide to conversion rate optimisation explains how.

How Much Does Google Ads Cost?

Costs vary by industry, location and competition. Some keywords cost very little per click; competitive ones like insurance, law and finance can be expensive. Focus on cost per conversion and return on ad spend, not just cost per click.

Common Google Ads Mistakes

  • Using only broad keywords without negatives.
  • Sending traffic to the homepage instead of a relevant landing page.
  • Not tracking conversions.
  • Setting and forgetting campaigns.
  • Targeting too wide a location.
  • Giving up after a few days — campaigns need time to learn.
Google Ads SEO
Speed Immediate traffic Takes months
Cost Pay per click Time and content investment
Longevity Stops when you stop paying Can bring traffic for years
Control High targeting control Depends on rankings

Many businesses use both: ads for immediate results and SEO for long-term growth.
