An SEO agency is a company that specializes in providing search engine optimization (SEO) services to other businesses. These services typically involve helping businesses improve their ranking on search engines like Google, which can help them attract more organic traffic to their website. This can be done through a combination of on-page optimization (making sure a website's content and structure is optimized for search engines) and off-page optimization (building high-quality backlinks to a website from other reputable websites). An SEO agency can also provide other services, such as keyword research and analysis, content creation, and technical SEO audits. The goal of an SEO agency is to help businesses improve their visibility and ranking on search engines, which can lead to increased organic traffic and potential growth.
