Pay-per-click (PPC) advertising lets you appear at the top of Google and other platforms within hours, and you only pay when someone clicks. It is one of the fastest ways to generate leads and sales, but it can also waste money quickly without the right setup. This PPC advertising guide covers how PPC works, how to choose keywords, which campaign types to use and how to improve your return on investment.
What Is PPC and SEM?
PPC is a model where advertisers pay each time an ad is clicked. Search engine marketing (SEM) usually refers to paid advertising on search engines such as Google and Microsoft Bing. Google Ads is the largest PPC platform, but the same principles apply to Microsoft Ads, Meta, LinkedIn and others.
How Google Ads Decides Who Shows and What You Pay
When someone searches, Google runs an auction among advertisers targeting that search. Your position and cost depend on:
- Your bid: the maximum you are willing to pay, or the target set by automated bidding.
- Quality: Google estimates expected click-through rate, ad relevance and landing page experience. Higher quality can lower your costs.
- Ad assets and format: sitelinks, callouts and other assets can improve visibility.
- Context: device, location, time and the search itself.
This means a well-structured campaign with relevant ads and good landing pages can beat competitors who simply bid more.
Step 1: PPC Keyword Research
Keywords decide when your ads appear. Focus on searches that show buying intent.
- Start with services and products in customer language, plus locations if you serve specific areas.
- Use Google Keyword Planner to find variations, estimated volume and typical bid ranges.
- Prioritise high-intent terms such as “near me”, “price”, “quote”, “book” and “hire”.
- Choose match types carefully. Exact and phrase match give more control; broad match can find new searches but should be paired with smart bidding, strong conversion tracking and careful monitoring.
- Build negative keyword lists to block irrelevant searches such as “free”, “jobs”, “course” or competitor names you do not want.
Step 2: Choose the Right Campaign Types
- Search campaigns: text ads on Google results. Best for capturing people actively looking for your service.
- Performance Max: one campaign that uses Google’s automation across Search, YouTube, Display, Gmail, Discover and Maps. Powerful for ecommerce and lead generation when tracking is solid.
- Shopping campaigns: product listings with images and prices for online stores.
- Display and remarketing: visual ads to reach people who visited your site.
- Video (YouTube): awareness and consideration, especially for products that benefit from demonstration.
Most businesses should start with focused Search campaigns, then expand once they have conversion data.
Step 3: Structure Campaigns Clearly
Group keywords by theme so each ad group has closely related searches and matching ads. For example, an agency might have separate ad groups for “local SEO services”, “technical SEO audit” and “SEO packages”. This improves relevance, Quality Score and reporting.
Step 4: Write Ads That Earn Clicks
- Include the main keyword or service in headlines.
- State a clear benefit or differentiator: speed, price, guarantee, experience.
- Add a direct call to action such as “Get a Free Quote”.
- Use all relevant assets: sitelinks, callouts, structured snippets, call and location assets.
- Provide several headline and description variations so responsive search ads can test combinations.
Step 5: Optimise for Mobile
Many PPC clicks come from phones, so mobile performance can make or break a campaign.
- Send traffic to fast, mobile-friendly landing pages.
- Use call assets so mobile users can phone you in one tap.
- Keep forms short and easy to complete on a small screen.
- Review performance by device and adjust bids or budgets if one device converts much better.
Step 6: Track Conversions Properly
Without conversion tracking, you cannot know which keywords and ads make money. Track form submissions, calls, WhatsApp clicks, bookings and purchases using Google Ads conversion tracking and Google Analytics 4. Import offline conversions from your CRM if sales happen later by phone or in person.
Step 7: Improve ROI Over Time
- Review search terms weekly and add negative keywords.
- Pause poor performers and move budget to keywords with the best cost per conversion.
- Test landing pages: headlines, offers, forms and trust signals.
- Use smart bidding such as Maximise Conversions or Target CPA once you have enough conversion data.
- Adjust schedules and locations based on when and where customers convert.
Common PPC Mistakes
- Sending all traffic to the homepage instead of a relevant landing page.
- Running broad match without negative keywords or conversion tracking.
- Judging success by clicks rather than leads and sales.
- Setting campaigns up and never reviewing them.
