Surfer SEO has revolutionized how agencies approach content creation.

This allows agency writers and editors to optimize content with surgical precision. The 'Audit' feature is particularly useful for agencies looking for quick wins; it compares an existing page to the top 10 results and identifies specific gaps in word count, heading usage, and keyword density.
