"# Comparison between Commercial and Free Backlink CheckersOne of the most common inquiries is about finding backlinks, distinguishing between spammy and legitimate backlinks, sources of backlinks, and whether commercial SEO tools that are free are worth using.
Bing Webmaster Tools
Even though Bing is smaller than Google, it still has access to the entire web and provides backlink information for all domains. Unlike Google Search Console (GSC), which only shows sample reports, Bing Webmaster Tools (BWT) displays backlinks for all domains.
Authentication via GSC is possible, eliminating the need for new meta or domain setup to access BWT.
Identifying Non-Spammy Backlinks
SEMrush may display more backlinks, but some are of low value. Link spam from high-quality domains is what matters, not a cluster of blogspot pages. Bing excludes these low-value links, allowing users to view all domains.
For more details, search “free backlink checker primary position” or “bing free SEO tools primary” for keywords and a free SEO health scanner. Authentication through GSC is also an option."
