Overview
About LinkBuilder.io
LinkBuilder.io is a specialist link building agency founded in 2016 with its main office in Edinburgh and a second office in St. Petersburg, Florida. Its 40-plus staff run managed outreach, guest post, broken-link and PR-led link campaigns, mostly for US and UK SaaS and tech companies, plus white-label work for agencies. Monthly packages start at $5,999.
LinkBuilder.io launched in 2016 and lists its main office on March Road in Edinburgh, with a second office in St. Petersburg, Florida. Clutch records Edinburgh as its headquarters with 21 to 30 staff there, and the company’s own about page puts the wider team at 43 link building specialists. It has kept the same single-service model since launch and reports more than 350 companies helped and over 20,000 links built.
This is a link building agency rather than an all-round SEO firm. Clients buy managed monthly campaigns that combine relationship-based editorial outreach, guest posts, broken link building, resource page outreach and PR-style pitching, backed by content support where a link needs a home. The Pro plan costs $5,999 a month for 16 or more links with an average domain rating of 50 to 90, and the Growth plan is $9,999 for 26 or more links plus internal linking and toxic backlink audits. Agencies can buy white-label links on custom terms.
Most of its customers are US and UK software and tech companies. Clutch names Udemy, SoFi, Tripadvisor, SolarWinds, RapidAPI and The Bouqs Co., and the site shows LegalZoom and Drip plus a testimonial from the co-founder of content agency Grow and Convert. Of 14 Clutch reviews averaging 4.6, most report organic traffic or authority gains; one SaaS client cited around 30% more organic traffic and top-three rankings. One August 2026 review scored 0.5, saying the links were not niche-relevant and rankings did not improve.
Buyers get a large, specialised team dedicated to one hard SEO task, with clear volumes and prices. The weaknesses are narrow scope and the usual link-quality risk, so agree on relevance criteria and approval rights for target sites before starting.

Editor’s take
A strong option for funded SaaS and tech firms, or agencies, that need outsourced link acquisition at scale. Businesses wanting full-service SEO or with small budgets should look at generalist agencies.
