Majestic vs Ontolo in 2026: backlink intelligence vs link prospect discovery
Majestic tells you what a link profile is worth, tracing Trust Flow back to 2006. Ontolo tells you which sites might link to you next, crawling 80+ sources at 250,000 prospects a minute, and can even import a Majestic export directly.
Majestic
Ontolo- Majestic measures link quality through Trust Flow and Citation Flow, tracing link paths back to a seed set of trusted domains. Ontolo has no equivalent quality metric; it discovers and categorizes prospects rather than scoring links that already exist.
- Ontolo natively accepts CSV or plain-text exports from Majestic, so a Majestic backlink list can be dropped directly into Ontolo's prospect categorization engine.
- Majestic has a free tier for basic lookups and published pricing up to €94.99/month for Pro. Ontolo has no public pricing page and requires direct contact to get a quote.
- Ontolo prospects from 80+ sources simultaneously at 250,000 prospects per minute with automatic query expansion. Majestic's Site Explorer only analyzes backlinks that already exist; it has no discovery or crawling function for new prospects.
- Majestic's Author Explorer identifies editorial contributors and traces their placement history across the web, useful for digital PR targeting. Ontolo's categorization instead classifies prospects by where a keyword appears on the page, article body versus navigation or footer.
- Majestic offers API access on the Pro plan through separate credits. Ontolo has no documented API; its primary output is a multi-tab, color-coded Excel export.
- Majestic's Topical Trust Flow scores a site's link equity across more than 800 topic categories. Ontolo has no topical relevance scoring, though it filters prospects by whether a keyword sits in article content versus boilerplate.
Majestic and Ontolo get grouped as backlink tools, but they analyze different things. Majestic is a specialist link-intelligence platform: its Trust Flow and Citation Flow metrics score the quality of links that already exist, drawing on a Historic Index stretching back to 2006 and a Fresh Index updated multiple times daily. Ontolo doesn't score anything that already exists; it discovers link prospects you haven't contacted yet, querying 80+ sources simultaneously and expanding a single search term like "guest post" into 20-plus variations automatically. Majestic has no prospecting function, and Ontolo has no quality-scoring metric of its own, though it will happily import a CSV of Majestic data and apply its own categorization on top. One is an analysis engine, the other a discovery engine, and the workflow overlap is smaller than the shared "backlink tool" label suggests.
The tools at a glance
Majestic
Backlink intelligence specialists since 2004 with the largest historic index and proprietary Trust Flow and Citation Flow metrics
Majestic runs two indexes: a Fresh Index covering roughly the last 120 days, updated multiple times daily, and a Historic Index reaching back to 2006 with over 4.5 trillion crawled URLs, the deepest retrospective backlink dataset commercially available. Its signature metrics, Trust Flow and Citation Flow, score link quality and link volume separately, and the ratio between the two is a widely used shorthand for spotting manipulative link profiles.
Topical Trust Flow extends that scoring across more than 800 topic categories, so you can judge not just how trustworthy a linking domain is but how relevant its topic focus is to yours. Author Explorer, a Majestic-exclusive, identifies editorial contributors by name and traces their publication history, useful for finding journalists and writers with a track record of placements in your niche.
What Majestic doesn't do is find you anything new. There's no prospecting, no query expansion, no way to discover a link opportunity you haven't already got in front of you through Site Explorer or a bulk backlink search. Pricing starts free for basic lookups, with Lite at €46.99/month unlocking higher Fresh Index volume and Pro at €94.99/month adding the Historic Index and Raw Data Exports.

Ontolo
Deep link prospecting engine that discovers and categorizes prospects from 80+ sources at 250,000 prospects per minute
Ontolo does the opposite job: instead of scoring links you already have, it finds sites that might link to you. A single search term like "guest post" automatically expands into more than 20 related query variations behind the scenes, and the tool crawls 80+ sources simultaneously, processing prospects at up to 250,000 per minute with sub-second search across the resulting database.
Its categorization goes deeper than most prospecting tools, distinguishing whether a target keyword or social link appears in article content versus a site's navigation or footer, which cuts down on prospects that only technically match a search term. It also accepts CSV or plain-text uploads from Ahrefs, Moz, or Majestic, so a list you've already pulled from a quality-analysis tool can be run through Ontolo's classification engine rather than starting from scratch.
There's no Trust Flow equivalent inside Ontolo, no way to judge the authority of a discovered prospect without exporting the list and checking it elsewhere, and no outreach or link-tracking features once a campaign starts. Pricing isn't public; you have to contact the team directly, and the interface still reflects the product's 2008 origins.

Which should you choose?
MajesticOntoloMajesticOntoloMajesticMajesticThese two rarely compete for the same budget line because they sit on opposite sides of the same decision. Majestic answers whether a link, or a potential linking domain, is actually worth having, with metrics that are widely understood across the SEO industry. Ontolo answers who you could ask in the first place, at a prospecting depth and speed few tools match, and it's explicitly built to consume a Majestic export rather than compete with it. A team with plenty of prospects but no way to judge which ones are worth pursuing has a Majestic-shaped gap; a team that already knows what a good link looks like but is running out of sites to pitch has an Ontolo-shaped one.
Bottom line
If the real bottleneck is judging link quality, whether that's auditing your own profile, vetting a prospect list, or doing penalty-recovery research against the Historic Index, Majestic's free tier is worth testing before anything else, with Pro at €94.99/month unlocking the full historic depth. If the bottleneck is running out of well-qualified sites to contact in the first place, Ontolo's 80-plus source crawl and query expansion solves a different problem that Majestic doesn't attempt, though you'll need to contact the Ontolo team directly since pricing isn't public. Agencies doing serious link building at volume tend to end up using both: Ontolo to build the prospect list, Majestic to decide which prospects on it are actually worth an email.
Frequently asked questions
What's the actual difference between Majestic and Ontolo if both call themselves backlink tools?
Majestic analyzes links that already exist, scoring their quality with Trust Flow and Citation Flow and drawing on a Historic Index back to 2006. Ontolo does the opposite: it discovers link prospects you haven't contacted yet, crawling 80+ sources and expanding search terms into dozens of query variations. Neither one does the other's job, so calling them competitors is a stretch; they sit at different stages of the same link building pipeline.
Can I import a Majestic export into Ontolo?
Yes, Ontolo natively accepts CSV or plain-text uploads from Majestic, along with Ahrefs and Moz, and applies its own categorization and search engine on top of the imported data. This is useful if you've already pulled a list of domains from Majestic and want Ontolo's classification, distinguishing article-body mentions from navigation or footer placements, applied to it.
Does Ontolo have anything like Majestic's Trust Flow to judge prospect quality?
No, Ontolo has no quality-scoring metric comparable to Trust Flow or Citation Flow; its categorization sorts prospects by where a keyword or social link appears on the page, not by domain authority or link quality. Teams using Ontolo for prospecting typically export the list and run it through Majestic or a similar tool separately to judge which prospects are actually worth pursuing.
Why doesn't Ontolo publish pricing the way Majestic does?
Ontolo requires direct contact to get a quote, with no public pricing page, unlike Majestic, which lists every tier from a free plan up to €94.99 a month for Pro. This reflects Ontolo's older, more sales-assisted origins as a product operating since 2008, whereas Majestic has built a fully self-serve pricing structure with a free entry point for basic lookups.
Is Majestic worth it if I already use Ahrefs or SEMrush for backlink data?
Majestic is worth adding specifically for its Historic Index and Author Explorer, since Trust Flow and Citation Flow give a different quality lens than domain rating scores from other tools, and the Historic Index back to 2006 goes deeper than most alternatives. Teams that already have a keyword-focused platform often run Majestic alongside it rather than instead of it, since Majestic has no keyword research or rank tracking of its own.
How current is Ontolo as a product in 2026?
Ontolo has been operating since 2008 and the product still appears to be taking new signups, though its interface and public footprint haven't kept pace with newer prospecting tools, and its site references activity dating back to 2016. Anyone evaluating it seriously should contact the team directly to confirm current pricing and product status rather than assuming feature parity with a more actively marketed competitor.
