Value of Backlinks Changes Over Time as Sites Grow in Size & Adds More Links
Backlinks don’t lose their value directly because of their age, but PageRank is distributed more broadly over time as the linking site publishes pages and increases the volume of links.
Unlinked Brand Mentions Don’t Pass Any Value
If a web page mentions your brand, but doesn’t link to your site, it won’t pass any value.
PageRank Can be Passed Through Meta Refresh Redirects But They’re Not Advised
Avoid using meta refresh as a redirect as these can have accessibility issues, especially when a 301 redirect can be used instead. If Google can recognise a meta refresh redirect PageRank will be passed across though.
Links Not Visible by Default Will Still Pass PageRank if They’re in HTML
Google will only process and pass PageRank for links that are in the HTML, which also applies to links not visible by default.
Links to Different Language Sites Provide Same Value as Same Language Links
Links to a different language site provide the same value as links to same language sites.
Different Country Versions of Content Can Dilute Value of Original Content
Creating different country versions of pages in the same language can dilute the value of the original content and mean that other sites may rank for this term. John recommends working with people who have experience of working with large international sites so you can get the balance right of having pages that are useful to visitors in different countries while not the diluting value of these pages.
Link Position Doesn’t Influence Weight
Google doesn’t give more weight to internal links based on their position on a page.
Place Links to Important Pages Higher in a Site Hierarchy
Make sure links to your most important pages are relatively high up in a site hierarchy so Googlebot and users can reach them quickly and so Google can pass Pagerank more quickly.
Google Recognises When a Different Site is Launched on an Old Domain
When a new site appears on a domain that was previously used by a different site or company, Google attempts to recognise it as a different site.
