Link Signals Checker
Check all key backlink authority metrics for any domain — DA, PA, Trust Flow, Citation Flow, and referring domains in one report.
A link signals checker is the starting point for any link building campaign. According to Google’s documentation on links and search, links remain one of the most important signals for understanding page importance and relevance.
Enter any domain and get a complete link authority report: Domain Authority (DA), Page Authority (PA), Trust Flow, Citation Flow, total backlinks count, and number of unique referring domains. Use it to evaluate potential link partners, monitor your own link growth, or spy on competitor authority.

Link Building Best Practices
Quality over quantity — follow these rules to build links that actually move your rankings.
Target Niche-Relevant Sites
A DA 40 link from a site in your exact niche is worth more than a DA 80 link from an irrelevant site. Use it to verify niche relevance before outreach.
Diversify Anchor Text
Keep exact-match anchor text under 10% of your link profile. Over-optimization of anchor text is a major red flag to Google’s Penguin algorithm.
Grow Referring Domains
100 links from 10 domains is weaker than 100 links from 100 different domains. Google values unique referring domains above raw link count.
Fix Internal Link Gaps
Internal links are free link equity. Link from your high-authority pages to your pages that need a rankings boost — this works immediately without outreach.
Disavow Toxic Links
Spammy backlinks from PBNs or link farms can trigger Google penalties. Identify and disavow them via Google Search Console.
Monitor Link Velocity
Gaining 500 links in one week after months of zero looks unnatural to Google. Build links at a consistent, gradual pace for sustainable ranking growth.
