  • Ensure pages have a good level of unique content.
  • Create an HTML sitemap for users.
  • Create an XML sitemap.
  • If relevant, include an xml sitemap index, which lists the location for a blog sitemap perhaps generated by WordPress, the main sitemap & a video sitemap (this would be a lower maintenance method, as the blog sitemap would be automatically updated).
  • Link XML sitemap (or XML sitemap index) from the robots.txt file.
  • Verify with Google Webmaster tools (for both www. and non www. versions of the site, and any subdomains).
  • Verify with Bing Webmaster tools.
  • Link blogger profile pages up with the bloggers’ Google plus page.
  • Ensure all your bloggers have a Google Plus profile.
  • Keep JavaScript in a separate file & minify.
  • Keep CSS in a separate file & minify.
  • Use image sprites for template images that are used across the site.
  • Ensure images are all compressed – Smushit  lets you compress a batch of images in folder a structure.
  • Ensure images have alt text.
  • Use a content delivery network (CDN) for images/media – this can be a subdomain or Amazon cdn for example.

  • Enable gzip compression.
  • Create an error page with user friendly message, navigation, search box.
  • Ensure each page has unique title tag, meta description.
  • Check for broken links, update any within your control and create 301 redirects from the old to the new.
  • Force trailing slashes across urls (except after a file name in the URL – e.g. /example-case-study.pdf).
  • Add in the canonical tag to the header of each page e.g. <link rel=”canonical” href=”http://www.example.com/”/>.
  • Choose and use an address format consistently across owned properties & external listings.
  • Use Microformats for structured data – e.g. recipes, address details, reviews and review aggregates.
  • Add Web Analytics tracking (customise if required – e.g. to include re-marketing & subdomain tracking).
  • Link through to the relevant pages elsewhere on the site where mentioned.
  • Implement Open graph so that when someone links to site content on Facebook or G+ you have more control over title, description & images.
  • Add a favicon and include in your header.
