Your site audit should include:

  • Checking Indexed pages perform a site search and not how many pages are returned. Your homepage should be top of the list of your site search, if not, there could be issues or penalties.
  • Organic Landing Pages within Google Analytics you are able to view your best and least performing landing pages, if your pages are not indexing within Google they may have errors connected to them.
