What Does an SEO Agency Do?

An SEO agency manages the ongoing work of ranking a website in organic search: keyword research, technical audits, on page optimization, content production, and link building. Most run this as a monthly retainer rather than a one time project, because search rankings respond to sustained effort, not a single fix.

Day to day, that means tracking rankings and traffic, publishing new pages targeted at buyer keywords, fixing crawl errors, and reporting progress to the client. Good agencies also advise on site structure and conversion, since ranking traffic that does not convert is not worth much to the business paying for it.

Many agencies now run the research and writing side of that retainer through SEO software built for agencies so one strategist can manage far more client sites.
