The domain locust.io was registered on October 21, 2011, through gandi sas and uses Cloudflare for DNS and security. At 14 years old, it signals established credibility, a mature online presence, and accumulated authority that contribute to stronger trust signals, improved SEO potential, and a proven track record in search visibility.
The backlink profile for Locust shows a strong presence of medium-authority sources (DA in the 40–69 range) alongside at least one DA 70+ high-authority referral (notably a prominent developer resource on GitHub), and links coming from developer resources, technology publications, and community sites like Stack Overflow and Medium that are relevant to the product. This mix of reputable, topical referrals contributes positively to Locust’s organic search performance by signaling topical relevance and trust to search engines, supporting overall SEO strength despite a modest Trust Score and room to grow in broader high-authority coverage.
The sample linkset is heavily weighted toward nofollow links with an approximate 90:10 dofollow:nofollow split (mostly nofollow from GitHub entries and a dofollow from Stack Overflow), meaning only a minority of links directly pass link equity while the high-authority dofollow links still transfer meaningful authority. Anchor text is overwhelmingly branded or keyword-rich (approximately 100% branded/keyword-rich, 0% naked URLs, 0% other), which is common for developer tool mentions but could benefit from more variety to appear fully natural and capture broader keyword relevance.
