How does Google find that xyz.com has good backlinks for a specific category?

Google uses complex algorithms and machine learning models to determine the quality and relevance of backlinks to a specific category or topic. Here are some factors that Google considers:

1. Relevance: Google evaluates the relevance of the content of the page where the link is located to the category or topic in question. For example, if the link is on a page about fitness, Google would consider it more relevant for a website that focuses on fitness.
2. Authority: Google considers the authority of the website that links to the category or topic in question. The more authoritative the website is, the more valuable the link will be.
3. Anchor text: The text that is used to link to the website is also important. If the anchor text contains relevant keywords related to the category or topic, it can help Google understand the relevance of the link.
4. Diversity: Google also looks for diversity in the backlink profile. A website with a diverse range of high-quality backlinks from different sources is considered more valuable than a website with a large number of low-quality backlinks from a single source.
5. Naturalness: Google tries to identify backlinks that are created naturally, rather than those that are manipulated for the purpose of improving search rankings. Links that are obtained through spammy tactics, such as buying links or participating in link schemes, are generally considered low-quality and can result in a penalty from Google.
