# ShipDR > Backlink tracker for directory submissions. Makers submit their product to > startup and AI directories; ShipDR verifies every listing (live, dofollow, > indexable), catches backlinks that drop or flip to nofollow, and charts the > site's Ahrefs Domain Rating history. $10 one-time per website, no > subscription. Key facts: - The directory pool is audited by hand and ranked by maker-proven results: verified live listings from real products, machine-read, never self-reported. Directories cannot pay to be listed or ranked. - Verification reads the listing page itself: backlink presence, rel value, indexability. JS-rendered pages are checked in a real browser. Checks run on a risk-based schedule (hottest backlinks every 6 hours) and on demand. - ShipDR never promises that Domain Rating will rise: DR is Ahrefs' metric. It verifies the work and records what happened. Pages: - https://shipdr.dev/ : product overview, live directory teaser, pricing - https://shipdr.dev/directories : the directory ledger (three rows free) - https://shipdr.dev/pricing : $10 once per website, FAQ - https://shipdr.dev/tools : index of all ten free checkers - https://shipdr.dev/tools/hreflang-checker : free tool, validates hreflang tags and fetches every alternate to verify the return links most sets miss - https://shipdr.dev/tools/noindex-checker : free tool, reads a page's meta robots, meta googlebot and X-Robots-Tag to say whether Google may index it - https://shipdr.dev/tools/dofollow-link-checker : free tool, fetches a page that links to yours and reports the anchor's rel (dofollow, nofollow, ugc, sponsored) plus whether the page itself is indexable - https://shipdr.dev/tools/domain-rating-checker : free tool, looks up any domain's Ahrefs Domain Rating (Domain Rating by Ahrefs) - https://shipdr.dev/tools/canonical-checker : free tool, reads a page's canonical from both the tag and the Link response header, and flags conflicting, cross-domain or missing ones - https://shipdr.dev/tools/meta-tag-checker : free tool, reads the whole head (title, description, robots, canonical, viewport, lang, social tags) and previews how the result reads - https://shipdr.dev/tools/sitemap-checker : free tool, validates an XML sitemap, checks the robots.txt declaration, and catches lastmod dates that are build stamps rather than real edits - https://shipdr.dev/tools/open-graph-checker : free tool, reads og and twitter tags, previews the share card, and fetches the og:image to catch broken ones - https://shipdr.dev/tools/redirect-chain-checker : free tool, walks a redirect chain hop by hop and reports each status, destination and X-Robots-Tag, including hops that ask not to be followed - https://shipdr.dev/tools/robots-txt-checker : free tool, parses robots.txt the way Google does (most specific group, longest path, Allow wins ties) and reports per crawler whether a path may be fetched, search and AI crawlers alike (GPTBot, ClaudeBot, PerplexityBot, Google-Extended, CCBot) ## Guides - https://shipdr.dev/guides : index of the guides below - https://shipdr.dev/guides/directory-submission-seo : what a directory listing is actually worth, the four failure modes that make most submissions produce nothing, the four checks that decide whether one is worth doing, and where the channel stops paying - https://shipdr.dev/guides/dofollow-vs-nofollow : dofollow is the absence of a rel rather than a value you write; why nofollow is not a bad backlink and is only a bad trade when a homepage slot paid for it; and why a dofollow link on a noindex or robots-blocked page still passes nothing - https://shipdr.dev/guides/how-long-backlinks-take : the five stages between a submission and a link that counts (submitted, published, crawled, indexed, counted), what stalls each one, and why "how long" is usually the wrong question - https://shipdr.dev/guides/link-equity : what link equity is (a chain of permissions rather than a substance), the four conditions a link must meet before it passes anything, why a break is total, and the redirect case that looks like a clean dofollow link - https://shipdr.dev/guides/lost-backlinks : the four ways a backlink dies (page gone, link removed, rel changed, page stopped being readable), why the quiet three are worse than the loud one, and how to catch them without a paid backlink index - https://shipdr.dev/guides/domain-rating-vs-domain-authority : DR is Ahrefs, DA is Moz, Google uses neither; why the same site scores differently on each, and why both are easy to inflate with reciprocal links - https://shipdr.dev/guides/rank-on-chatgpt : answer engines have no rankings and publish no factors; what is checkable is crawler access per agent (GPTBot vs OAI-SearchBot, Google-Extended is not a crawler), indexability, and whether a self-contained answer can be lifted from the page - https://shipdr.dev/guides/ai-crawlers : every AI crawler is a separate name with a separate job (GPTBot trains, other agents fetch at answer time, Google-Extended is not a crawler); the most-specific-group rule that makes files say what nobody intended; and the trade behind blocking each, stated as a judgement rather than a best practice - https://shipdr.dev/guides/toxic-backlinks : toxicity scores are vendor opinions, not search engine signals; random spam links pointing at you are ignored; the only two cases where disavow is warranted are a manual action and links you built or bought yourself - https://shipdr.dev/guides/backlink-outreach : what comes after directory submissions stop paying; who is worth asking and why; and the check to run on a target page before writing, since plenty of pages could never have given a link that counts - https://shipdr.dev/guides/link-exchanges : why the limit on reciprocal links and badge swaps is a share of your dofollow profile rather than a count, what a swap costs that a one-way link does not, and the three things that must all be true for one to earn anything (dofollow, indexable, crawlable) - https://shipdr.dev/guides/how-many-backlinks : why no number of backlinks can be given honestly, why referring domains beat raw link counts, the four things that actually decide it, and how to tell whether the links you already count are real Contact: support@shipdr.dev
