Linkee vs Ontolo in 2026: full-workflow outreach automation vs pure prospecting depth
Linkee covers prospecting, contact finding, and outreach for $80.83/month with published pricing. Ontolo goes deeper on prospecting alone, from 80+ sources at 250,000 prospects a minute, with no public pricing.
Linkee
Ontolo- Ontolo prospects from 80+ sources simultaneously with automatic query expansion into 20+ variations per search. Linkee draws from its own 5M+ database plus CSV import from Ahrefs or SEMrush, but does not crawl 80 external sources live.
- Linkee finds and verifies contact emails and sends outreach sequences natively. Ontolo has no email finder, no sender, and no CRM; it hands off a multi-tab Excel export for you to run outreach elsewhere.
- Ontolo has no public pricing page and requires direct contact to get a quote. Linkee publishes exact pricing from $80.83/month for the Essential plan.
- Ontolo processes prospects at 250,000 per minute with sub-second search across your resulting database. Linkee does not publish a comparable prospecting throughput figure.
- Linkee's AI relevancy checker scores prospects against your target keywords. Ontolo's classification goes deeper structurally, distinguishing keyword mentions in article body content from navigation, footer, or comment placements.
- Ontolo accepts CSV or plain text uploads from Moz, Ahrefs, and Majestic for cross-tool workflows. Linkee accepts CSV import specifically from Ahrefs and SEMrush.
- Ontolo has been operating since 2008 with an interface that reflects that era. Linkee is a newer AI-native platform with automated follow-up scheduling and Gmail, Outlook, and SMTP integration built in.
Linkee and Ontolo both promise a bigger, cleaner prospect list, but they stop at different points in the workflow. Linkee runs the whole pipeline: it prospects from a 5 million-plus site database, scores relevance with AI, finds and verifies contact emails, and sends the outreach sequence, all for a published $80.83 a month. Ontolo does one thing and stops there. It prospects from more than 80 sources simultaneously, expands your search into 20-plus query variations automatically, and classifies results down to whether a keyword appears in article content or site navigation, then hands you a multi-tab Excel export and nothing else: no email finder, no CRM, no outreach automation, and no public pricing page. If prospecting depth is your bottleneck, Ontolo goes further than Linkee does. If you need the whole workflow in one tool, Linkee is the only one of the two that gets you there.
The tools at a glance
Linkee
AI-powered link building automation from prospecting to outreach
Linkee covers the full acquisition workflow in one platform. Choose a guest post or niche edit campaign, prospect from Linkee's own 5 million-plus site database or import a CSV from Ahrefs or SEMrush, and let the AI relevancy checker score each site against your target keywords while filtering out private blog networks, non-secure domains, and broken pages.
From there, Linkee finds and verifies contact emails directly from the prospect sites and runs a personalized outreach sequence through Gmail, Outlook, or SMTP, with automated follow-ups and custom send windows on every plan. Unlike a pure prospecting tool, nothing needs to be handed off to a second platform to actually contact anyone.
Pricing is public: Essential gives 10,000 credits and one project for $80.83 a month, Pro adds a CRM at $164.17 a month, and Agency unlocks unlimited seats and projects at $298.33 a month. The tradeoff for that convenience is prospecting depth; Linkee's database and query logic are not built to match a dedicated prospecting engine's source coverage.

|---|---|---|---|
| Credits per month | 10,000 | 25,000 | 60,000 |

Ontolo
Deep link prospecting engine that discovers and categorizes prospects from 80+ sources at 250,000 prospects per minute
Ontolo is a prospecting-only engine, operating since 2008, built for link builders who find that general-purpose tools don't go deep enough. It prospects from more than 80 sources simultaneously and automatically expands a search term like "guest post" into 20-plus related query variations, so you're not manually thinking through every phrasing a site might use to signal an opportunity.
Once prospects are crawled, Ontolo's custom-built search runs at sub-second speed across databases processed at 250,000 prospects a minute, and its classification system distinguishes keywords in article body content from navigation, footer, or comment placements, plus separates a site's own social accounts from social links embedded in article content. You can also upload CSV or plain text lists from Moz, Ahrefs, or Majestic and run the same categorization on top of your own data.
What Ontolo does not do is send a single email. There is no contact finder, no email sender, no CRM, and no integration with modern outreach platforms; prospect data leaves the tool as a multi-tab, color-coded Excel export for you to work from manually or hand off elsewhere. Pricing is not public, and the 2008-era interface and lack of recent visible updates mean prospective buyers should contact the team directly before evaluating.
| Feature | Plans Contact for pricing |
|---|---|
| Prospecting sources | 80+ |
| Processing speed | 250k/min |
| Query expansion | Yes |
| External list upload (Ahrefs, Moz, Majestic) | Yes |
| Excel multi-tab exports | Yes |
| Outreach / email sending | No |

Which should you choose?
LinkeeOntoloLinkeeOntoloLinkeeOntoloOntoloLinkee and Ontolo solve genuinely different problems inside the same broad category. Linkee is the practical choice when you want one subscription, one login, and a straight line from prospect to sent email, with pricing you can see before you talk to anyone. Ontolo is the choice when prospecting depth itself is the constraint: when Linkee's or Ahrefs' or SEMrush's source coverage isn't turning up enough qualified prospects and you need a tool built specifically to crawl more sources and classify results more precisely, even if that means exporting to Excel and running outreach through a separate platform.
Bottom line
Start with Linkee if you want prospecting, contact finding, and outreach running end to end without adding a second tool, and its published $80.83/month entry price is easy to evaluate against budget upfront. Contact Ontolo directly if your current prospect lists feel thin regardless of source and you're prepared to run outreach through BuzzStream, Respona, or another CRM once Ontolo hands you the export; just budget time to learn its interface and get a real quote before assuming it fits your price range.
Frequently asked questions
Does Ontolo send outreach emails the way Linkee does?
No. Ontolo has no email finder, no email sender, and no CRM of any kind; it is exclusively a prospecting and categorization engine. Once you export your prospect list from Ontolo as a multi-tab Excel file, you need a separate tool such as Linkee, BuzzStream, or Respona to actually contact anyone.
Why doesn't Ontolo publish pricing like Linkee does?
Ontolo requires direct contact or registration to get a quote, with no public pricing page listed anywhere on its site. Linkee, by contrast, publishes exact monthly pricing starting at $80.83 for the Essential plan. If comparing cost upfront matters to your evaluation, that's a real point in Linkee's favor.
Is Linkee's prospect database as deep as Ontolo's 80+ source engine?
Not by source count. Linkee prospects from its own 5 million-plus site database plus CSV import from Ahrefs or SEMrush, while Ontolo crawls more than 80 sources simultaneously with automatic query expansion into 20-plus variations. Ontolo is built specifically for prospecting depth; Linkee trades some of that depth for a complete outreach workflow in the same tool.
Can I import an Ontolo export into Linkee for outreach?
Linkee accepts CSV import specifically from Ahrefs and SEMrush exports; Ontolo's native export format is a multi-tab, color-coded Excel file rather than a flat CSV. You would likely need to reformat or extract the relevant columns from Ontolo's export before importing into Linkee, since the two tools were not built to hand off to each other directly.
Which tool is better for a beginner starting their first link building campaign?
Linkee is the easier starting point. It has a documented free trial with no credit card, published pricing, and a workflow that goes from prospecting straight through to sent outreach without switching tools. Ontolo's learning curve, 2008-era interface, and lack of outreach features make it better suited to experienced link builders who already know how to run the outreach half of the process elsewhere.
Does Ontolo work for niches outside standard guest posting, like resource page link building?
Yes. Ontolo's query expansion covers more than 90 prospect types, and its 80+ source coverage plus content-versus-navigation classification apply to resource page links, link insertions, and other prospect types beyond guest posts. Linkee is also built around guest post and niche edit campaign types specifically, so Ontolo has broader native prospect-type coverage on the discovery side.
