Free backlink checker tool. Enter any URL to check backlinks using top SEO tools: Ahrefs, Moz, Ubersuggest, SEMrush, and Majestic. Understand key metrics like Domain Authority, Trust Flow, Citation Flow, and referring domains. Essential for SEO analysis, link building, and competitor research.
Backlinks are one of Google's top 3 ranking factors. Each backlink from a reputable site acts as a 'vote of confidence' for your content. Quality matters more than quantity — one link from a DA 80 site is worth more than 100 links from spam sites. Analyzing your backlink profile helps you understand your SEO strength, identify link building opportunities, find and disavow toxic links, and benchmark against competitors.
Domain Authority (DA): Moz's score 0-100 predicting ranking potential. Page Authority (PA): score for a specific page. Trust Flow: Majestic's quality metric based on trustworthiness. Citation Flow: Majestic's quantity metric. Referring Domains: number of unique domains linking to you. Dofollow vs Nofollow: dofollow passes link juice; nofollow does not. Anchor Text: the clickable text of the link — should be natural and varied.
Each tool has its own database and crawl frequency. Using 2-3 tools gives a more complete picture of your backlink profile.
DA 20-30 is average, 40-50 is good, 60+ is excellent. Compare with competitors in your niche rather than aiming for an absolute number.
Check monthly for most sites. If you're actively building links or running a campaign, check weekly to track progress.
A toxic backlink comes from a spammy, low-quality, or penalized site. Too many toxic links can hurt your rankings. Use Google Search Console's Disavow tool to remove their influence.
Nofollow links don't pass PageRank directly, but they can still drive traffic and brand awareness. Google may also use them as a hint for crawling and indexing.
