PPC stands for Pay Per Click. It is a form of digital advertising where businesses pay when someone clicks on their advert.
The most common example is a Google Search ad, where a business appears at the top of the search results when someone searches for a product or service they offer. However, PPC now covers much more than traditional search ads. Paid adverts can appear across Google Search, YouTube, Display, Gmail, Discover, Maps, Shopping, social media platforms and other websites.
PPC is often used to drive targeted traffic, increase visibility, generate enquiries and support online sales. Unlike SEO, which usually takes time to build, PPC can help a business appear in front of potential customers much more quickly.
How Does PPC Work?
PPC works by allowing advertisers to show ads to people based on keywords, locations, audiences, interests, behaviours and online intent.
In a traditional Google Search campaign, a business chooses keywords they want to appear for. For example, a solicitor may want to appear when someone searches for “family law solicitor near me”, or an ecommerce business may want to appear when someone searches for a specific product.
When a search takes place, Google runs an ad auction to decide which ads are shown and in what order. This is not based on budget alone. Google also looks at the quality and relevance of the ad, the landing page experience and how useful the ad is likely to be for the person searching.
Google refers to this as Quality Score, which is a diagnostic measure scored from 1 to 10 at keyword level. A higher Quality Score generally means your ads and landing pages are more relevant to the user’s search.
PPC, SEO And SEM: What Is The Difference?
PPC and SEO both help businesses appear online, but they work in different ways.
PPC is paid advertising. You pay when someone clicks on your advert, and campaigns can usually start generating visibility quickly once they are live.
SEO, or Search Engine Optimisation, focuses on improving your organic visibility in search results. This involves improving your website content, technical performance, authority and relevance so that search engines can better understand and rank your pages.
SEM, or Search Engine Marketing, is often used as a broader term that can include both paid search activity and organic search activity.
In practice, PPC and SEO often work best together. PPC can bring in traffic and leads quickly, while SEO builds longer-term visibility. PPC data can also show which keywords, landing pages and search terms are most likely to convert, which can then help inform the wider SEO strategy.
What Are The Benefits Of PPC?
PPC can be a valuable channel for businesses that want to reach the right people at the right time.
The main benefits include:
- Fast visibility in search results
- Control over daily and monthly budgets
- Targeting by keyword, location, audience, device and schedule
- Clear tracking of clicks, enquiries, sales and return on spend
- The ability to test messaging, offers and landing pages
- Support for both short-term lead generation and wider brand awareness
- Useful data that can support SEO, content and wider marketing decisions
PPC is not just about getting more clicks. A strong PPC campaign should focus on attracting the right traffic and turning that traffic into valuable actions, such as form submissions, phone calls, purchases or bookings.
Main Types Of PPC Campaigns
Search Ads
Search ads appear when someone searches for a relevant product or service on Google or another search engine.
These ads are useful because they target people who are already showing intent. For example, someone searching for “emergency plumber in Winchester” or “Google Ads agency Hampshire” is likely to be much closer to taking action than someone who is simply browsing online.
Search campaigns usually rely on keyword targeting, strong ad copy, clear calls to action and relevant landing pages.
Performance Max
Performance Max, often called P-Max, is a goal-based Google Ads campaign type that allows advertisers to access Google’s advertising inventory from one campaign. This can include Search, YouTube, Display, Discover, Gmail and Maps. Google describes Performance Max as a campaign type designed to complement keyword-based Search campaigns and help advertisers find more converting customers across Google’s channels.
Performance Max uses automation and Google AI across bidding, audiences, creative assets and placements. It can be especially useful when there is strong conversion tracking, clear goals and enough data for Google to optimise towards.
However, Performance Max still needs proper strategy. It works best when the account has strong creative assets, clear audience signals, accurate conversion tracking and well-structured landing pages.
AI Max For Search
AI Max for Search is a newer Google Ads feature designed to bring more AI-led optimisation into Search campaigns.
Google describes AI Max as a set of targeting and creative enhancements, including improved search term matching, text customisation for headlines and descriptions, and final URL expansion to help match users to more relevant landing pages.
In simple terms, AI Max can help Search campaigns reach additional relevant searches beyond the exact keywords already added to the campaign. It can also help tailor ad text and landing page selection based on user intent.
This does not mean PPC can be left to run itself. AI Max still needs clear objectives, strong website content, accurate tracking, sensible controls and regular performance reviews.
Display Advertising
Display ads are visual ads that appear across websites, apps and online placements. They are often used for brand awareness, remarketing and staying visible to people who may be interested in your products or services.
Display campaigns are usually less intent-led than Search campaigns, but they can support the wider customer journey by keeping a brand visible before or after someone visits a website.
Remarketing
Remarketing allows businesses to show ads to people who have previously visited their website or interacted with their brand.
For example, someone may visit a product page, leave without enquiring, and then later see an advert reminding them of that product or service. Remarketing can be useful because it focuses on people who have already shown some level of interest.
Shopping Ads
Shopping ads are mainly used by ecommerce businesses. They show product information directly in Google, including images, prices, product names and retailer details.
Shopping campaigns rely heavily on the quality of the product feed. Product titles, images, descriptions, prices and availability all play an important role in performance.
Shopping activity can be managed through campaign types such as Standard Shopping or Performance Max, depending on the business goals and setup.
Paid Social Ads
PPC is not limited to Google. Platforms such as Meta, LinkedIn, TikTok and YouTube also allow businesses to run paid campaigns.
Paid social campaigns can be useful for brand awareness, lead generation, video views, ecommerce sales and remarketing. These platforms often use audience, interest and behaviour-based targeting rather than traditional keyword targeting.
Important PPC Metrics To Understand
A PPC campaign should be judged on more than clicks alone.
Some of the key metrics include:
- Impressions: how many times your ad was shown
- Clicks: how many people clicked your ad
- CTR: the percentage of people who clicked after seeing your ad
- CPC: the average cost per click
- Conversions: valuable actions such as enquiries, calls, purchases or bookings
- Conversion rate: the percentage of users who converted after clicking
- CPA: the cost to generate one conversion
- ROAS: return on ad spend, usually used for ecommerce campaigns
- Quality Score: a Google Ads diagnostic score that helps assess ad and landing page relevance
The most important metrics depend on the goal of the campaign. For lead generation, enquiry quality and cost per lead may matter most. For ecommerce, revenue and return on ad spend are usually more important.
Why Landing Pages Matter
A PPC campaign does not end when someone clicks the ad.
The landing page plays a major role in whether that click turns into an enquiry or sale. A good PPC landing page should be relevant to the advert, easy to use, fast to load and clear about the next step the user should take.
For example, if someone clicks an ad for “emergency boiler repair”, they should not be sent to a generic homepage. They should land on a page that clearly explains the emergency boiler repair service, the areas covered, trust signals, contact options and a strong call to action.
Good landing pages can improve conversion rates and help make ad spend work harder.
Why Conversion Tracking Is Essential
Conversion tracking is one of the most important parts of PPC.
Without it, it is difficult to understand which campaigns, keywords, ads and landing pages are generating real results. A campaign may receive lots of clicks, but if those clicks do not turn into enquiries or sales, the budget may not be working effectively.
Useful conversions can include:
- Contact form submissions
- Phone calls
- Email clicks
- Purchases
- Booking requests
- Live chat enquiries
- Quote requests
- Brochure downloads
Accurate tracking helps PPC campaigns optimise towards the actions that actually matter to the business.
How AI Is Changing PPC
PPC has changed significantly in recent years. Google Ads now uses more automation and AI across bidding, targeting, creative testing and campaign delivery.
Features such as Performance Max and AI Max are part of this shift. They allow advertisers to reach broader audiences, match to more searches and optimise across more placements. Performance Max uses Google AI across areas such as bidding, budget optimisation, audiences, creative and attribution.
This can be powerful, but it also means PPC management has changed. The role of a PPC specialist is now less about manually controlling every single bid and more about setting the right strategy, feeding the system good data, reviewing performance properly and making sure automation is working towards the right goals.
AI can help improve performance, but it still needs human input, commercial understanding and careful management.
What Makes A PPC Campaign Successful?
A strong PPC campaign usually includes:
- Clear goals
- Relevant keyword and audience targeting
- Strong ad copy
- Sensible budget planning
- Accurate conversion tracking
- Well-structured campaigns
- High-quality landing pages
- Ongoing search term reviews
- Negative keyword management
- Regular performance analysis
- Testing and optimisation over time
PPC is not a one-time setup task. Campaigns need to be reviewed, refined and improved based on real performance data.
Summary:
PPC is one of the most effective ways to increase visibility, drive targeted traffic and generate leads or sales online.
It allows businesses to appear in front of people who are actively searching, browsing or showing interest in relevant products and services. While traditional Search, Display and Shopping campaigns are still important, modern PPC now also includes campaign types and features such as Performance Max, AI Max, paid social, video and remarketing.
The best results usually come from a clear strategy, strong tracking, relevant landing pages and ongoing optimisation. When used properly, PPC can deliver quick visibility while also supporting wider SEO and digital marketing activity.
