Our verdict on ontolo

ontolo is a web-based prospecting platform for marketers and SEO professionals focused on link-building research. It discovers websites and pages from more than 80 sources, expands prospecting terms into related queries, then crawls and indexes newly discovered prospects. Teams can search indexed data with advanced queries, categorize and prioritize opportunities, extract contact emails, contact URLs, and social accounts, and examine followed and nofollowed outbound links. Its supported prospect types include directories, link lists, guest posts, blogrolls, link submissions, and content submissions.

The published plans are structured around index capacity and daily crawl volume. Pro costs $97 per month and includes 1,000,000 URLs in the index, 200,000 URLs per day, and a 30-day money-back guarantee. Agency costs $297 per month and raises capacity to 5,000,000 indexed URLs and 1,000,000 URLs per day, with the same 30-day money-back guarantee. Custom is designed for organizations needing custom code, custom data, or custom solutions. Data can be imported through URL lists and exported in Excel or CSV formats, giving research teams a practical path from discovery to analysis and handoff.

ontolo’s strongest fit is prospect research at scale, particularly when a team needs detailed filtering, categorization, contact extraction, and link-attribute analysis in one web-based workspace. It is less suitable for teams looking for a complete outreach workflow because verified outreach and monitoring are not part of its stated positioning. Organizations that need a focused discovery and research layer should find the Pro or Agency capacity relevant to their workload; teams prioritizing outreach execution or ongoing monitoring should consider a different category fit.
