Blocking Crawling of Parametered URLs in GSC Will Mean PageRank Will be Lost
Google sees links between two canonical URLs and if there is no canonical destination URL then it will be seen as going nowhere and won’t be used. Practically this isn’t an issue as links aren’t usually to a specific parameter variation, so it is unlikely to be driving a lot of the site’s PageRank.
Jump Links Are Used to Further Understand Page Structure Not Pass PageRank
Jump links, where you link from one part of a page to another part of that same page, are not something that Google will use to pass signals such as PageRank. Instead, they are used to further understand the structure of the page and can be shown in search results to link to a particularly relevant part of the page for a user’s query.
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.
