- Authority
- Relevance
- Anchor textual content
- Observe vs. nofollow
- Placement
- Vacation spot

Let’s have a look at them in additional element.
Authority
Backlinks from sturdy webpages often switch extra “authority” than weak ones.

We’ve studied page-level authority just a few occasions, and we’ve discovered a transparent relationship between it and natural site visitors.

Sidenote.
URL Ranking (UR) is Ahrefs’ page-level authority metric. It’s scored on a scale from 0 to 100.
That stated, backlinks from sturdy pages don’t all the time switch extra authority.
The extra hyperlinks there are on the web page that hyperlinks to you, the much less authority can be transferred to you as a result of it’s shared between all of these pages (because of the PageRank algorithm).
You’ll be able to gauge a backlink’s authority by utilizing the UR metric within the Backlinks report in Ahrefs’ Website Explorer. (You may as well discover it in different Ahrefs instruments the place related.) The upper the UR, the higher.

Relevance
Hyperlinks from web sites on the identical subject as yours are deemed to deliver extra worth. Google states this in its “How Search Works” guide:
If different distinguished web sites on the topic hyperlink to the web page, that’s an excellent signal that the knowledge is of top quality.
Say a plumber has backlinks from two pages: one about cats, and one about putting in boilers. Relevance on this context implies that chances are high the latter hyperlink is Most worthy.

Anchor textual content
Anchor textual content refers back to the clickable phrases that type a backlink.

Google says that anchor textual content influences rankings in its original patent.
Google employs a lot of methods to enhance search high quality, together with web page rank, anchor textual content, and proximity data.
You’ll be able to see the anchor textual content of any backlink in Website Explorer’s Backlinks report.

Observe vs. nofollow
Nofollow is a hyperlink attribute that instructs Google to not comply with the hyperlink and serves as a trace to not cross authority (as of 2019).

A adopted hyperlink is a hyperlink that doesn’t have that attribute nor the “sponsored” or “UGC” attributes.
As a result of nofollow hyperlinks often don’t affect rankings, it’s finest to prioritize getting adopted hyperlinks.
Nevertheless, since “nofollow” is barely a touch now, pursuing a nofollow hyperlink from a related high-authority web page should still be an excellent concept.
You’ll find a majority of these backlinks utilizing filters in Website Explorer’s Backlinks report.

Placement
As a result of persons are extra more likely to click on prominently positioned hyperlinks, some hyperlinks on webpages doubtless cross extra authority than others.

Invoice Slawski talks about this in his analysis of Google’s up to date “affordable surfer” patent:
If a hyperlink is in the primary content material space of a web page, makes use of a font and shade which may make it stand out, and makes use of textual content which will make it one thing doubtless that somebody would possibly click on upon it, then it might cross alongside a good quantity of PageRank. Then again, if it combines options that make it much less more likely to be clicked upon, reminiscent of being within the footer of a web page, in the identical shade textual content as the remainder of the textual content on that web page, and the identical font sort, and makes use of anchor textual content that doesn’t curiosity folks, it could not cross alongside plenty of PageRank.
Contemplate this when pursuing hyperlinks. In case your hyperlink will doubtless find yourself within the web site’s footer or together with 50 different websites within the sidebar, then put your power into different alternatives.
