If someone tells you to check whether a backlink is “high quality,” the first question might be: what exactly am I supposed to check?
A backlink is simply a link from another website to yours, but evaluating its quality means looking more closely at that particular link. You want to understand where it comes from, what the page around it is discussing, why the link appears there, and whether the page it leads to makes sense in that context.
This is why backlink quality cannot be understood by looking at one number or one part of the link. A website might look impressive while the backlink itself appears in unrelated content, or a smaller website might contain a link that fits naturally into a highly relevant discussion.
What Does the Linking Page Have to Do With Yours?
Start with the relationship between the two pages. Read the page containing the backlink and compare its subject with the page the link leads to. They do not need to cover exactly the same topic, but there should be a reasonable explanation for why someone reading one might benefit from visiting the other.
This relationship is commonly described as topical relevance. A backlink from an article about SEO analysis to a guide about evaluating backlinks has an understandable connection, while a link to a completely unrelated subject would be harder to explain.
Relevance therefore tells you something that a domain metric cannot: whether the two pages actually make sense together.
What Happens When You Read Around the Link?
Once the relationship between the pages is clear, look more closely at the backlink itself by reading the sentence and paragraph around it. Does the writer use the destination as a source, an example, supporting information, or a useful place for the reader to learn more?
If so, the surrounding content helps explain why the backlink is there. A relevant page can still contain a link that feels disconnected from the particular discussion where it appears, so checking the immediate context adds another part to the evaluation. This is one of the quality signals that can help when examining a backlink.
Does Placement Add Anything to the Picture?
After reading around the backlink, look at where it appears on the page. A link inside the main discussion is often easier to understand because the surrounding sentences can show why the writer introduced it.
That does not mean a link outside the main content is automatically low quality. Placement gives you more information about how the backlink functions on that particular page, rather than acting as a rule that makes one location good and another bad.
What About the Website Behind the Page?
Now widen the view and look at the website providing the backlink. Consider what kind of site it is, what it normally publishes, and whether the page containing the link appears to have a genuine purpose for readers.
This is also where third-party authority metrics can provide additional information, but those numbers are measurements created by SEO tools rather than Google quality scores. A high metric can therefore tell you something about how a particular tool views the website without answering the questions you have already asked about the backlink itself.
