mxverify

mxverify is a free, browser-based backlink value checker that helps SEO professionals, link builders, content marketers, and site owners estimate what a single followed backlink from any website is worth in ranking benefit, expressed in dollars. Rather than showing a seller's asking price, it calculates a BV score using the same model used by bklink.uk to value links in its audits. The tool is positioned as an independent, no-sign-up research utility for pre-purchase due diligence, competitive link analysis, and digital PR evaluation. Its target audience includes SEO agencies, affiliate marketers, bloggers, publishers, and businesses that buy or sell guest posts, sponsored posts, niche edits, and other link placements. Core features include instant BV scoring, detailed link-type breakdowns (A editorial, B guest/sponsored, C neutralised/user-generated/nofollow, D network), site strength based on authority and organic traffic, relevance multipliers, traffic, server, age, outbound linking behaviour, public reports, audited link histories, and network detection. Content features include methodology explanations, example reports like google.com, recently valued sites, top lists, publication audits, and shared-server network verdicts. User experience is simple: enter a domain, click check, and receive a public report without registration. Technical features include a proprietary valuation formula (BV 2.8), Ahrefs authority data integration, log-scale traffic scoring, audit-based link type inference, caching/reuse of figures for up to 30 days, and a cookie-choice analytics notice. mxverify does not sell links, does not accept payment for listings, and clearly states limitations. It is maintained by Palash Bagchi, founder of bklink, and is listed across numerous SaaS and startup directories.
