1. Introduction

If you’ve ever searched online for ways to grow your business, you’ve probably come across the term “SEO.” But what exactly does an SEO agency do, and why do so many UK businesses partner with them?

Whether you’re new to digital marketing or considering hiring an agency, this guide will break down everything you need to know about SEO agencies: their role, services, and how they help your business grow.

2. What Is an SEO Agency?

An SEO agency is a digital marketing company that helps businesses increase their visibility on search engines like Google. Their goal is to improve your rankings for specific keywords so that your ideal customers can easily find you online.

3. What Do SEO Agencies Actually Do?

Here are the core services a professional SEO agency provides:

1. Keyword Research

They find the terms your target audience is searching for, including high-volume and low-competition keywords tailored to your business.

2. On-Page SEO

This includes optimizing your website’s content, headings, meta titles/descriptions, internal linking, and image alt texts.

3. Technical SEO

Agencies ensure your website loads fast, is mobile-friendly, has a clean URL structure, and is easy for search engines to crawl and index.

4. Local SEO

For location-based businesses, agencies set up and optimize your Google Business Profile, build local citations, and boost local map rankings.

5. Link Building

SEO agencies secure high-authority backlinks through outreach, guest blogging, citations, and digital PR — essential for ranking.

6. Content Strategy & Writing

They plan and create content (blogs, service pages, guides) that ranks well and drives traffic.

7. Analytics & Reporting

Agencies track performance with tools like Google Analytics, Search Console, and SEMrush to measure keyword rankings, traffic, and conversions.
