Online SEO retainers work well for most businesses because SEO isn't a one-time project. Rankings decay without maintenance, competitors launch new content, and Google updates algorithms roughly every few weeks. A retainer keeps someone consistently monitoring your site, fixing technical issues as they appear, publishing optimized content, and building authority through links and PR. The alternative—hiring ad-hoc whenever traffic drops—costs more and loses months of compounding progress. The quality of a retainer depends entirely on structure. Good retainers specify exactly what you get each month: number of optimized pages, backlinks acquired, technical audits completed, and keyword rankings tracked. They bill month-to-month or quarterly, so you can leave if results stall. Bad retainers lock you into 12-month contracts with deliverables like "ongoing optimization" that mean nothing measurable. If an agency won't show you last month's work in a shared tracker or dashboard, that's a red flag. Typical Canadian retainers range from $1,500/month for local service businesses (10–15 hours of work) up to $8,000–$15,000/month for competitive e-commerce or national brands. Anything under $1,000/month usually means offshore execution or extremely limited scope—maybe rank tracking and a blog post, but no serious link acquisition or technical SEO. Anything above $20,000/month should come with a dedicated strategist and developer hours. At Ottawa SEO Inc., we run retainers for most clients in the $2,500–$6,000 range because SEO requires continued effort across technical, content, and authority. We bill monthly, share a live task board, and expect clients to see measurable keyword movement within 90 days. If you're not seeing new rankings or organic traffic growth by month four, either the strategy is wrong or the market is more competitive than scoped—and a good agency will tell you that directly and adjust, not just keep billing. The retainer model works when both sides treat it like a partnership with clear expectations, not a black-box service contract.
