Why Check Backlinks?
You should check backlinks because they affect how much search engines and AI search platforms trust your site and whether your pages appear in search results.
By checking your website's backlinks, you see whether your key pages have earned links from other sites.
Backlinks often explain why some pages have high visibility in Google and AI search results while others don't.
By checking competitor backlinks, you can compare their backlinks with yours and see whether they have more links from strong, relevant sites.
Comparing backlinks helps you understand if your competitor gets more visibility because of a stronger link profile and how big that gap is.

Review link statuses to see new and lost backlinks over time. If you're running campaigns or working with an agency, this helps you see whether those efforts are actually adding relevant, high quality links.Find new link opportunities from competitors

Cómo obtenemos datos precisos de Backlink
We get accurate backlink data by crawling the web with our own web crawler, storing the backlinks we find in a large, frequently updated database, and cleaning and assessing that data before you see it.
Our crawler visits billions of pages, finds new links, and adds them to a backlink index of more than 43 trillion backlinks and 390 million referring domains.
This is the same database that powers Backlink Analytics and the rest of our SEO tools.
The database is refreshed at least hourly, so when you check backlinks, you're working with the most recent data for your site and your competitors.
To keep the data accurate, we remove duplicate links, filter out obvious noise, and calculate Authority Score using signals like backlink quality and quantity, estimated organic traffic, and signs of manipulation.
This process reduces bad, inaccurate data and keeps each site's backlink profile as reliable as possible.
Your website needs more than just backlinks.
