What is PPC (Pay-Per-Click)?, explained properly.
What is PPC?
PPC (pay-per-click) is a digital advertising model where you pay a fee each time someone clicks one of your ads. The most common application is paid search, where ads appear above or below organic results for the keywords you bid on. It delivers qualified traffic as soon as the campaign launches.
How PPC actually works
You identify relevant search queries, create targeted ads and set maximum per-click bids. The platform runs a real-time auction with each search, and you pay only on actual clicks. Platforms rank ads using bid amount, ad relevance and quality scores based on historical click-through rates and landing page performance. Google Ads dominates by spend volume. Microsoft Advertising (Bing) operates at a smaller scale with frequently lower costs and growing relevance thanks to ChatGPT integration. Meta Ads and LinkedIn use the same per-click model on social feeds instead of search results.
The main forms of PPC
- **Search ads:** text ads above or below organic results for relevant queries. The highest-intent format. - **Display ads:** image and banner ads across the Google Display Network on millions of partner sites. Lower intent, broader reach. - **Shopping ads:** product-image ads in search results, drawn from product feeds. Critical for ecommerce. - **Video ads:** skippable and unskippable ads on YouTube and the wider video network. - **Performance Max:** Google's AI-driven multi-channel campaign mixing all formats based on conversion data. - **Local Services Ads:** a separate Google product for trades and local services using a pay-per-lead model.
Why use PPC alongside SEO
SEO works over the long term while PPC delivers short-term results. SEO builds future visibility; PPC attracts buyers today. Relying on either alone leaves revenue untapped. PPC bridges the gap while SEO develops, PPC testing reveals which keywords convert to inform organic targeting, and SEO captures the demand PPC generates. The two work best under one team with shared data.
What good PPC looks like
- **Tight query, ad and landing page alignment:** a user searches X, the ad mentions X, the landing page addresses X. Quality scores reward this. - **Functional conversion tracking:** without attributing sales to specific keywords, you are guessing. - **Negative keywords:** actively blocking unprofitable searches, nearly as important as your targeted keywords. - **Regular bid management:** weekly human review or well-configured automated bidding. - **Realistic budgets:** sub-threshold budgets produce noise, and most categories need a minimum of around 1,500 pounds a month for actionable data.
What is PPC (Pay-Per-Click)?: common questions.
How much does PPC cost?
Keyword competition determines cost. Average cost per click ranges from around 0.50 pounds in low-competition niches to over 30 pounds in saturated sectors like legal and insurance. Most small businesses see meaningful results from monthly budgets of 1,500 to 8,000 pounds. Below 1,000 pounds a month, sparse data prevents reliable optimisation.
Is PPC better than SEO?
Both serve distinct purposes. PPC delivers predictable leads quickly but stops when the budget stops. SEO takes months to mature but generates compounding traffic at near-zero marginal cost. Most businesses benefit from running both at once, adjusting the mix as SEO gains momentum.
What is a good PPC conversion rate?
Average PPC search conversion rates across industries sit around 4% to 5%. Local service businesses frequently achieve 8% to 15% on well-targeted campaigns, while ecommerce typically converts 1% to 3%. Your own historical performance, not external benchmarks, sets your baseline, with steady improvement as the real goal.
Can PPC hurt my SEO rankings?
No. Google has repeatedly confirmed that paid spend does not influence organic rankings. Buying ads does not lift organic performance, and pausing campaigns does not penalise it. There is an indirect overlap through user experience: well-converting landing pages improve both PPC quality scores and SEO signals like time on page and bounce rate.
“I've had the pleasure of working with Chris on several SEO projects for my websites in the health field. He was definitely been able to demystify things so that I felt able to make decisions with him and feel confident they were the right ones. For a non-techie, that is worth gold! I look forward to working with Chris again and warmly recommend him to anyone who - like me - is unsure about all things SEO.”
“I was recommended by my branding partner to use Chris and his team last year. I can’t recommend them highly enough. They are very responsive , easy to communicate with and great at translating techy stuff when needed. They are now an essential part of my business model”
“We've been working closely with Chris, Hannah and the team for over 12 months now. As a small company with ambitious growth plans, it was incredibly important that we made the right choice on who to trust with our SEO. 18 months later, we're totally thrilled with our experience so far and our growing online presence within our market. We'd happily recommend BTT and their services to other SMEs. Drop them an enquiry!”
