Built by people who build links for a living

What we do

LinkBuildingServices.org is a research-led directory of link building services. We track 82 providers across 19 ranked lists, maintain a price dataset of 253,527 placements, and update rankings as providers change their prices, terms and methods.

Every provider has a full review: what it sells and for how much, its contract terms, its ratings on review platforms, and the sources behind each figure. 78 of them are scored and ranked in the overall list and the agency directory. The 4 citation services are reviewed but left out of both, because they sell business listings rather than links.

Why this site exists

Search for the best link building service and most of the pages that come back are lists written by one of the companies on them, or roundups with no prices, no method and no date. A ranking like that can't be checked, which makes it hard to trust with a budget of several thousand dollars a month.

We publish the parts those lists leave out. The scoring method and its weights are public. Every price is tied to a named source and the date we checked it. Our price study is built from 253,527 real listings rather than a vendor's rate card. And the complaints, weak spots and awkward contract terms we find stay on the page, including for providers near the top of a list.

What we cover

Link building is sold by very different kinds of businesses, and a fair comparison has to say which kind each provider is. The directory covers:

The 19 ranked lists sort those providers by the job a buyer has in mind: 10 by industry, such as SaaS, ecommerce and casino and iGaming; 5 by tactic, such as guest posting, niche edits and digital PR; and 4 by buyer, such as agencies, enterprise and startups. The category index has all of them.

• 37 managed link building and SEO agencies, which run outreach and placement for you
• 18 link marketplaces, where you pick each site and its price yourself, some with a managed option
• 9 productized services, which sell links by tier or package at a fixed price
• 14 digital PR firms, which earn coverage and links through stories and data
• 4 citation services, which build local business listings

How a review gets made

Research comes first. Asif reads each provider's pricing, terms and service pages, its sample reports and case studies, and its profiles on Clutch, G2, Trustpilot and similar platforms, then records every figure with its source and the date it was checked.

The provider is then scored on the same six weighted criteria as everyone else, from link quality to support. Before anything is published, the editor reads the page against its sources: each claim needs one, criticism has to be specific, and the score has to follow the method rather than a hunch.

Once a page is live, its byline shows who researched it, who checked it and when. Facts are re-checked at least quarterly and whenever a provider or reader reports a change; the latest full pass finished on October 15, 2026. The details are in our methodology and editorial policy.
