SEO vs PPC: Which Is Right for Your Business?

This is one of the most common questions we get asked: should I invest in SEO or PPC? The honest answer is that it depends on your business, your budget, your timeline, and what you’re trying to achieve. Both work. Both have strengths and weaknesses. And for many businesses, the best results come from using them together.

 

We run both SEO and Google Ads campaigns for our clients, so we don’t have a horse in this race. We recommend whatever makes commercial sense. This guide explains how both channels work, when each one makes sense, and how to decide where to put your budget.

 

What Is the Difference Between SEO and PPC?

 

SEO (Search Engine Optimisation) is the process of optimising your website to rank higher in Google’s organic (unpaid) search results. You don’t pay Google for the clicks. Instead, you invest in improving your website’s content, technical setup, and authority so that Google chooses to rank your pages. Results take time to build but are sustainable once achieved.

 

PPC (Pay Per Click) is paid advertising, most commonly through Google Ads, where you bid to show your ad at the top of search results for specific keywords. You pay every time someone clicks on your ad. Results are immediate, but they stop the moment you stop paying.

 

Both channels put your business in front of people who are actively searching for what you offer. The key differences are cost structure, timeline, and longevity.

 

When Does SEO Make More Sense?

 

SEO tends to be the better long-term investment for most businesses. Here’s when it makes the most sense:

 

You want sustainable, compounding returns. Unlike PPC where traffic stops when the budget runs out, SEO traffic keeps coming once you’ve earned your rankings. A page that ranks on page 1 today can continue generating traffic and leads for months or years with relatively low ongoing investment. Over time, the cost per lead from SEO drops significantly because you’re building an asset.

 

Your cost per click on Google Ads is high. In competitive industries like law, finance, insurance, and some home services, Google Ads clicks can cost £10 to £50+ per click. At those rates, the maths often favours investing in SEO to rank organically for those same terms. We’ve had clients where a few months of SEO investment has replaced thousands of pounds in monthly ad spend.

 

You want to build credibility and trust. Many users skip the ads and click on organic results because they trust them more. Ranking organically signals to potential customers that your business is established and relevant, not just willing to pay for visibility.

 

You’re in a market where people research before buying. For considered purchases where buyers do their homework (choosing a solicitor, finding a financial adviser, selecting a builder for a major project), being visible in organic results across multiple informational and commercial search queries builds familiarity and trust over time.

 

When Does PPC Make More Sense?

 

PPC has its own strengths, and there are situations where it’s the right choice:

 

You need results immediately. If you’ve just launched a new website, a new product, or you need leads this week, PPC delivers instant visibility. SEO takes months to build. PPC can have you at the top of Google within hours of setting up a campaign.

 

You’re testing a new market or offer. PPC is excellent for testing whether a keyword or a new service generates demand before committing to a long-term SEO strategy around it. You can run a campaign for a month, see if the clicks convert, and use that data to inform your SEO priorities.

 

You’re targeting very specific, time-sensitive campaigns. Seasonal promotions, events, limited-time offers, or anything with a fixed deadline is better suited to PPC. You can turn it on and off as needed. SEO doesn’t work on that kind of schedule.

 

You’re in a market where organic is dominated by large brands. For some nationally competitive terms, the organic results are locked down by massive websites with enormous authority. PPC lets you appear above all of them, provided you’re willing to pay for the clicks.

 

How Do the Costs Compare?

 

This is where it gets interesting, and where SEO often wins on a cost-per-lead basis over the medium to long term.

 

With PPC, your cost is directly tied to the number of clicks you receive. If a click costs £5 and you get 200 clicks a month, that’s £1,000 in ad spend alone, plus the management fee if you’re using an agency. If you stop paying, the traffic stops immediately.

 

With SEO, your cost is the monthly investment in optimisation (typically starting from £495 + VAT per month with us). The traffic it generates doesn’t cost per click. Once you rank, those clicks are effectively free. Over 12 to 24 months, the cumulative traffic from SEO almost always costs less per lead than PPC, especially in competitive industries where click costs are high.

 

The trade-off is time. PPC delivers from day one. SEO takes months to build but costs less per lead once it’s established. The right metrics will show you exactly which channel is delivering better ROI for your specific business.

 

Can You Use SEO and PPC Together?

 

Absolutely, and this is often the smartest approach. Here’s how they complement each other:

 

Use PPC for immediate visibility while SEO builds. When we start a new SEO campaign, the first few months are focused on technical fixes, content optimisation, and building authority. During that time, PPC can fill the gap and generate leads while the organic rankings catch up. As the SEO takes hold, you can gradually reduce your ad spend on the terms you’re now ranking for organically.

 

Use PPC data to inform your SEO strategy. Google Ads shows you exactly which keywords convert and which don’t. That conversion data is gold for keyword research. If a keyword converts well on PPC, it’s worth investing in ranking for it organically. If a keyword gets clicks but no conversions, you know to avoid targeting it with SEO.

 

Dominate the search results page. When you appear in both the paid ads and the organic results for the same term, you take up more space on the page and look more authoritative. Studies have consistently shown that brands visible in both positions get more total clicks than they would from either position alone.

 

Which Should You Start With?

 

If you can only afford one, and you’re thinking long-term, start with SEO. It builds an asset that keeps generating returns. If you need leads immediately and have the budget, start with PPC and add SEO as soon as you can.

 

If you have the budget for both, run them in parallel. Use PPC for quick wins and market testing while your SEO campaign builds the organic foundation underneath. Over time, the SEO takes over as the primary traffic source and PPC becomes a supplementary tool for specific campaigns or competitive terms.

 

The worst approach is to do neither. Your competitors are already visible on Google, either through ads, organic rankings, or both. Every day you’re not showing up is a day your potential customers are finding someone else instead.

Frequently Asked Questions

 

Is SEO cheaper than PPC?

Over the long term, usually yes. SEO requires a consistent monthly investment, but the traffic it generates doesn’t cost per click. Once you rank well, your cost per lead decreases over time. PPC costs remain constant or increase as competition grows. For most businesses, SEO delivers a better ROI over 12 to 24 months.

 

Can I stop doing SEO once I rank on page 1?

You can reduce the investment, but stopping entirely is risky. Competitors don’t stop. Google’s algorithm changes regularly. Without ongoing maintenance, your rankings will eventually decline as competitors overtake you. Think of SEO as maintenance rather than a one-off project.

 

Do people click on Google Ads or organic results more?

Organic results receive the majority of clicks overall, but ads capture a significant share for commercial search terms. The split varies by industry and query type. For highly commercial terms where the top three results are all ads, paid results can capture 30-40% of clicks. For informational queries, organic dominates. Having visibility in both gives you the best coverage.

 

How much should I budget for PPC?

It depends entirely on your industry, the keywords you want to target, and your local competition. Some businesses can run effective campaigns on £500 a month in ad spend. Others in competitive sectors need £2,000 or more. The key is to start with a realistic test budget, measure the results, and scale based on what’s working.

 

Will doing PPC help my SEO rankings?

No. Google has confirmed that running Google Ads does not directly influence your organic rankings. They are completely separate systems. However, PPC can indirectly support SEO by driving traffic that increases brand awareness, and by providing keyword conversion data that helps you make better SEO decisions.
