We start with the obvious best practices like fixing broken links and implementing a clean XML sitemap. We look for low-effort, high-impact solutions like utilizing NOINDEX tags or Robots.txt to mitigate low-quality content.
As we address low-hanging fruit, we delve into the technical infrastructure of your site to understand how you are presenting the contextual relationships among your pages. If you are relying on plugins or legacy code that is negatively impacting page performance (and therefore ranking potential) we root out the source.
