What is a backlink?
A backlink is a link from another website to your site. Search engines use backlinks as signals of credibility and relevance.
Why are backlinks important for SEO?
Quality backlinks can improve rankings, speed up page discovery, and increase topical authority when they come from trusted websites.
What is a linking domain?
A linking domain is a unique website linking to you. Diversity across relevant linking domains is often more useful than repeated links from one site.
Does this tool show real-time backlink data?
The tool requests the latest report available from the Semrush Backlinks API and caches successful results for six hours to control API usage.
Why can’t a free tool guarantee accurate backlinks without an API?
Backlink discovery requires a large crawler and maintained link index. Without a real API, backlink numbers would be guesses.
What is Semrush Authority Score?
Authority Score is Semrush’s metric from 0 to 100 for evaluating the overall quality and SEO strength of a domain or webpage.
What are follow and nofollow backlinks?
Follow links can pass ranking signals. Nofollow links contain an attribute telling search engines not to treat them as a standard endorsement.
Can I check multiple sites at once?
Yes. Bulk Mode compares up to 10 domains in one Semrush API request.
What should I do if backlink counts differ across tools?
Different providers use different crawlers and indexes. Compare movement over time instead of expecting identical totals.
How do I improve backlinks safely?
Publish useful content, earn relevant mentions, build partnerships, use digital PR, and avoid spammy link schemes.
