How many SEO agencies are there in the UK?

The UK has no exact, official count of pure SEO-only agencies, but industry data provides reliable proxies. IBISWorld reports 33,167 SEO & Internet Marketing Consultant businesses in 2024, representing the broadest measurable group offering SEO as a core service. While this category includes content marketing and general digital consulting, it remains the most accurate indicator of how many firms actively sell SEO in the UK.

Additional industry categories reinforce the scale of the market which is over 8,000 digital advertising agencies, more than 7,600 digital marketing agencies, and 25,000+ total marketing companies. With SEO now a standard line item across digital services, the practical number of UK companies providing SEO easily exceeds 30,000.

How to find the best SEO agencies in the UK?

SEO agencies in the UK are mainly based in key cities such as London, Manchester, Birmingham, Sheffield, Leeds, and Lancaster, where many well-known companies serve both local and national clients. Some agencies also focus on working with universities and schools, helping them improve course pages, research content, and student-recruitment visibility. Cities like Cardiff and nationwide providers also support this growing area.

To find a good SEO agency, start by defining your goals and researching options through SEO directories, LinkedIn, or cold emailing. Sites like SelectedFirms list top agencies, and booking early consultations helps you understand their process, expected results, and how well they fit your needs.

What services do UK SEO companies provide?

UK SEO companies offer a wide range of services to help businesses increase their online visibility, improve search engine rankings, and bring in more customers. Their work includes fixing technical issues, improving website content, building authority, and supporting both local and international growth.

The core services you can expect from the best SEO companies in UK

Technical SEO: Improves how a website performs behind the scenes. This includes fixing slow loading times, making sure the site works well on mobile, solving crawl and index issues, adding structured data, and improving overall site structure so search engines can easily read and understand the website.

On-Page SEO: Focuses on improving elements on each page such as meta titles, descriptions, headers, image alt text, and internal links. Agencies also work on page content to make it clearer, more relevant, and easier for search engines to match with user searches.

Off-Page SEO: Builds a website’s authority and trust by earning high-quality backlinks from reputable sites. This often involves outreach, digital PR, guest posting, and partnerships—helping the site rank higher by increasing its credibility.

Keyword Research: Identifies the best keywords customers are searching for. Agencies look for high-intent, relevant keywords that match the client’s industry and goals, helping improve visibility for terms that matter most.

Content Marketing: Creates and improves content such as blogs, guides, videos, and infographics. This content is designed to answer user questions, bring in more organic traffic, and support higher search rankings.

Local SEO: Helps businesses appear in local search results by optimizing Google Business Profile, improving local citations, managing reviews, and using local keywords. This is vital for companies targeting customers in specific areas.

Which industries usually prefer to hire UK SEO companies?

UK SEO companies work with a wide range of industries because strong online visibility is essential for almost every business today.

Agencies help improve local search visibility, manage online reviews, and optimize mobile experiences so businesses can attract both local visitors and international travellers.

Agencies help optimize articles, improve site structure, and plan content topics that match what readers are searching for, supporting long-term audience growth.
