An SEO consultant is a search engine optimization expert who evaluates how well a site ranks in Google and other engines, identifies what's holding it back, and maps out fixes. Unlike agencies that bundle services or in-house staff who handle one company's needs full-time, consultants usually work project-based or on retainer, advising multiple clients simultaneously. They bring outside perspective and specialized skills without the overhead of a permanent hire. Core responsibilities include technical audits (crawl errors, site speed, mobile usability, schema markup), keyword research and content gap analysis, backlink profile review, and competitor benchmarking. A good consultant delivers a prioritized roadmap showing which changes will move the needle first, whether that's fixing redirect chains, rewriting thin pages, or reclaiming lost links. Some implement changes hands-on if the client lacks dev resources; others hand off recommendations to internal teams and QA the execution. Consultants typically charge hourly rates between CAD 150 and 400, or monthly retainers from CAD 2,000 to 10,000 depending on scope and seniority. One-time audits often run CAD 3,000 to 8,000. You're paying for pattern recognition across dozens of past projects—they've seen your exact penalty or indexing issue before and know the three-step fix, whereas an agency account manager might escalate it internally and bill extra discovery hours. At Ottawa SEO Inc., we operate as both agency and consultant depending on client needs. For portfolio sites in our 500-plus domain network, founder Martin Vassilev acts as lead consultant, applying the same forensic approach we use for retainer clients. The main tradeoff: consultants rarely execute large-scale content production or link outreach themselves—they diagnose and direct, so you still need in-house capacity or contractors to turn strategy into live changes. If you want someone to own outcomes end-to-end, an agency model fits better; if you need expert diagnosis and a clear playbook your team can execute, a consultant is the efficient choice.
