Q: What is a backlink?

A backlink is a link from one website to another. Backlinks are one of the most important ranking factors in search engines. When a reputable website links to yours, it signals to Google that your content is trustworthy and authoritative.

Q: What is a dofollow vs nofollow link?

A dofollow link passes link equity (also called 'link juice') to the target page, helping it rank higher. A nofollow link includes a rel='nofollow' attribute, which tells search engines not to pass ranking credit. Both types are valuable — dofollow for SEO, nofollow for referral traffic.

Q: How many backlinks does a website need?

There is no universal number. What matters is the quality and relevance of backlinks, not just quantity. A domain with 100 high-quality backlinks from authoritative sites can outrank one with 10,000 low-quality links. Use our backlink checker to analyze the quality of any domain's link profile.

Q: What does our backlink data include?

Our database tracks over 8.5 billion backlinks across 46 million domains. For each backlink, we show the source URL, anchor text, rel attributes (dofollow/nofollow), link position, and the source domain. Data is refreshed with each crawl cycle.

Check the top backlinks pointing to any website.
