Over time, the website content you have (blog posts, galleries, service pages, etc.) will no longer hold the same search relevancy it once did. That is because search intent changes, particular keywords become obsolete, your competitors publish better content on the subject and more.
A free website SEO audit identifies where your top pages and keywords rank against your competitors. The audit also provides insight on ways to update your web pages to best match user search intent and provide a seamless webpage experience with valuable information that separates you from your competitors.
For example, a blog post buried past the first page of search results could be re-optimized with new longtail voice search queries, video, images, and a proper heading structure to regain web traffic.
