As an SEO expert, I can explain that an SEO agency is a specialised marketing firm that focuses on helping businesses achieve higher search engine rankings and increased online visibility through search engine optimisation (SEO) strategies. Essentially, an SEO agency works to optimise a website so that it ranks higher on search engine results pages (SERPs), driving more traffic to the site and ultimately contributing to business growth.

An SEO agency typically offers a range of services designed to improve website visibility and rankings on search engines like Google, Bing, and Yahoo. These services may include keyword research and analysis, on-page optimisation (such as improving website structure, meta descriptions, and title tags), off-page optimisation (such as link building and social media promotion), content creation, and local search optimisation for brick-and-mortar businesses.

SEO agencies may also help with improving the overall user experience of a website, providing analytics and reporting on website performance, and guiding businesses through the complex world of SEO. Additionally, some SEO agencies may offer expertise in other digital marketing areas, such as paid search (PPC), social media marketing, and content marketing.

In summary, an SEO agency is a specialised marketing firm that specialises in SEO services and tactics to help businesses improve their online visibility, increase website traffic, and ultimately grow their business. By partnering with an SEO agency, businesses can gain a competitive edge in the digital marketplace and better reach their target audience through optimised search engine rankings.
