SEO vs PPC: Which delivers better ROI for your marketing budget?

13 March 2024

Heading 1

The best way to drive traffic to your website for most businesses is through search engines, so it is essential to secure a prominent position on a Search Engine Results Page (SERP). The two ways to do this are through search engine optimisation (SEO) and pay-per-click (PPC) advertising.

The two options offer a different approach to generating leads and sales. Depending on what you are looking to achieve, either PPC or SEO might be better at reaching your business goals.

With PPC, businesses bid on relevant keywords to appear as a sponsored link at the top of SERPs. When visitors search for those keywords, the ad will be displayed in the sponsored results section. A business only pays for the ad if the link is clicked. The most popular ads are Google Ads, but advertising on Facebook, LinkedIn (ADD LINK - Why you need LinkedIn paid ads for your business (cotswoldweb.co.uk)) (ADD LINK - Facebook Ads: Measure your conversions! (cotswoldweb.co.uk)) or other social media can be just as effective, depending on your own target audience.

SEO is a long-term strategy to generate clicks without having to pay for them directly. It is about optimising your website content around relevant target keywords to convince a search engine that your business is a leading authority on a particular subject.

Here we will discuss the pros and cons of each, and which delivers the better return on investment (ROI) for your marketing budget.

One way to help you make a decision on which is the best option for your business is to check out the competition. They are targeting the same audience as you, so you can learn from their successes and their failures. If your competitors are investing heavily in PPC, it could indicate it would work well for your business too. And on the flipside, if they are ranking well in search results, investing in SEO could be the way forward.

PPC pros


  • PPC is the quickest way to appear at the top of the SERP.  Businesses pay to appear in a prominent position, generating instant visibility and traffic and, hopefully, instant sales and conversions. It works well for new products and new businesses, which haven’t had time to achieve a first page listing on search engines like Google or Bing.
  • PPC can work very well and be cost-effective for a small local business targeting a small geographical area with a small number of keywords.
  • PPC works well for products which need less research, which will often be lower value, higher volume items.
  • If your main business goal is brand awareness, PPC can give your business immediate visibility.
  • PPC gives you a lot of control over your messaging and targeting. This means you can target your ads to reach the exact demographic of your ideal buyer – from geographical location to industry type, age, gender, interests and more -  so your ads get seen by the right people at the right time, maximising your ROI. And if your ads aren’t working, you can change the content at short notice within your budget.
  • PPC gives you access to analytics so you can really track the performance of each individual ad and calculate your ROI. This means you can identify what works and what doesn’t, so you can allocate your budget to achieve the best possible results.
  • Advertisers have full control of their own PPC budget and can set daily or monthly spending limits. They can also adjust bids for specific keywords and pause campaigns when they want to.


PPC cons


  • PPC requires constant investment. It can be quite expensive, especially if you are bidding on a keyword popular with other businesses. Then you have to ask yourself whether you are really getting the ROI you want, particularly if the ad is for a low value product.
  • PPC is a short-term strategy – if you stop paying, your business will immediately disappear from searches. So your choices are either to start relying more on SEO or to keep paying for your ads!

SEO pros


  • SEO doesn’t incur direct costs per visit. If you can manage SEO within your business, it is ‘free’, with the only cost being staff time. A well optimised blog can bring visitors to your website for many years, saving money and reducing your reliance on paid ads.
  • Although paid ads will appear higher on searches than organic search results, visitors will usually trust organic searches more than adverts, so investing in SEO to get higher on searches could be a worthwhile investment.
  • SEO has long-lasting benefits. If your business can rank highly on Google or other search engines for relevant keywords, it can stay there for a sustained period of time, much longer than a short-term advertising campaign.
  • SEO creates high quality leads, as visitors will engage and read a lot of content before making a decision to buy.
  • Good SEO can improve your ROI over time – as you continue to produce optimised web content, your website will rise in the rankings, leading to more clicks and increased traffic.


SEO cons


  • SEO doesn’t bring instant results. It can take weeks and often months for search engines to crawl and index your website before it appears high up on SERPs.
  • There is no guarantee of success and, for competitive keywords especially, you may never see your website rank on the first page of Google.
  • If you need to outsource your SEO work, it can easily be just as expensive as PPC.
  • It is harder to track and calculate the ROI of SEO.
  • Search engines often change their algorithms without warning. This means something which ranked well yesterday is suddenly not as effective today, with your website plummeting in the rankings overnight. Staying on top of the changes in SEO can be time-consuming and costly.

Heading 1 Artificial intelligence (AI) has had a huge impact in many areas of life and SEO is no exception. While it has made online searches easier for consumers, keeping up with it and staying ahead as a business can be challenging. As Google integrates advanced AI into its search results, businesses must rethink their SEO strategies. Understanding the future of SEO in the context of AI is essential to appear high on search rankings and remain competitive. Traditionally, search engine optimisation (SEO) has relied largely on keyword optimisation and link building. If you sell garden products, you would make sure the phrase ‘garden products’ was used frequently throughout your website. You would also look to get some links back to your site from other websites – maybe other businesses in your local area or in a complementary sector. These traditional SEO methods are becoming less effective. AI means search engines like Google and Bing have become better at understanding the intent behind a search, through machine learning algorithms analysing huge quantities of data, as well as natural language processing. Natural language processing doesn’t just understand the words in a query, it understands the context and intent behind it. AI can even understand synonyms, slang and regional variation in language! When someone searches for something online, AI can analyse, interpret and predict their behaviour. So businesses have to adapt their SEO strategies to changing algorithms to stay competitive. You need to have a deeper understanding of your target audience and produce content which meets their needs and answers their queries. It is about providing the best answer to the questions your audience is asking, because AI algorithms are skilled at recognising content which meets the search intent of users and provides value. This means that content which is designed to meet specific needs, answer questions and provide the solutions to problems is more likely to rank higher in searches. AI algorithms will prioritise content which resonates with users on a human level – with every paragraph adding more value and depth. This aligns with AI’s preference for content which engages and informs – and also helps build a stronger connection with your target audience. In addition, AI is making voice searches (e.g. Alexa) much more effective. Voice searches tend to use more words than online searches e.g. ‘find me healthy snacks for pre-school children’ rather than just typing ‘healthy snacks’ into Google with no context. This aspect of AI will continue to grow in importance and become even more widely used.
