Frequently Asked Questions
How many backlinks does hydro.ac have?
The backlinks page for hydro.ac shows all individual inbound links discovered in our crawl of the web. Each backlink represents a hyperlink on another website that points to a page on hydro.ac. Use the filters to narrow results by dofollow/nofollow status, domain rating, or anchor text.
What is a backlink?
A backlink is a hyperlink on one website that points to a page on a different website. Backlinks are one of the most important ranking factors in search engine algorithms because they act as votes of confidence from other sites. The more high-quality backlinks a domain has, the more authority search engines assign to it.
Are the backlinks to hydro.ac dofollow or nofollow?
Backlinks to hydro.ac include both dofollow and nofollow links. Dofollow links pass link equity (ranking power) to the target site, while nofollow links include a rel="nofollow" attribute that tells search engines not to pass authority. Both types contribute to a natural backlink profile, but dofollow links carry more SEO weight. You can filter by link type using the rel filter above the table.
How often is backlink data updated?
Backlink data is updated monthly when our web crawler completes a new cycle. Our pipeline processes billions of web pages to discover new backlinks, track lost links, and update domain authority scores. The freshness of data depends on when our crawler last visited the referring pages.
