Importance of On-page links
It can affect both internal and external links and the link equity and link value that they pass to your website or to another website if you're linking out to them.
1. Content links tend to matter more
If we have a link down here in the content of the page pointing to my Choco Puffs or my Gummies page, that might actually carry more weight in Google's eyes than if we point to it in the navigation.
Now, this is not universally true, but observably, it seems to be the case. So when something is in the navigation, it's almost always universally in that navigation. When something is in here, it's often only specifically in here. So a little tough to tell cause and effect, but we can definitely see this when we get to external links.
2. Links in footers often get devalued
So if there's a link that you've got in your footer, but you don't have it in your primary navigation, whether that's on the side or the top, or in the content of the page, a link down here may not carry as much weight internally. In fact, sometimes it seems to carry almost no weight whatsoever other than just the indexing.
3. More used links may carry more weight
There are a lot of ways that Google might interpret that data or might collect it. It could be from the size of it or the CSS qualities. It could be from how it appears on the page visually. But regardless, that also seems to be the case.
4. Most visible links may get more weight
This does seem to be something that's testable. So if you have very small fonts, very tiny links, they are not nearly as accessible or obvious to visitors. It seems to be the case that they also don't carry as much weight in Google's rankings.
5. On pages with multiple links to the same URL
It turns out that Google will see both links. They both point to the same page in this case, both pointing to the same page over here, but this page will only inherit the value of the anchor text from the first link on the page, not both of them, that anchor text will essentially be treated as though it doesn't exist. Google ignores multiple links to the same URL. This is actually true internal and external. For this reason, if you're going ahead and trying to stuff in links in your internal content to other pages, thinking that you can get better anchor text value, well look, if they're already in your navigation, you're not getting any additional value.
