SEO services are the tactical work agencies and consultants perform to get your site ranking higher in organic search results. The core buckets are technical SEO (site speed, mobile-friendliness, crawl budget, schema markup), on-page optimization (title tags, headers, internal linking, content structure), content production (blog posts, landing pages, guides optimized for target keywords), off-page link building (earning backlinks from credible domains), and local SEO (Google Business Profile optimization, citation management, review generation for brick-and-mortar or service-area businesses). Most agencies package these into monthly retainers because SEO is ongoing—Google's algorithm shifts, competitors launch new content, and technical issues crop up. A typical retainer in Canada runs $2,000–$10,000/month depending on market competitiveness and scope. Smaller budgets focus on foundational fixes and a few pieces of content per month; larger engagements include aggressive link acquisition, multiple content assets weekly, and dedicated account management. Some providers offer project-based work: a technical audit ($1,500–$5,000), a one-time content cluster ($3,000–$8,000), or a local SEO setup ($1,000–$3,000). These make sense when you have in-house bandwidth to execute recommendations or you're testing an agency before committing to retainer. At Ottawa SEO Inc., we run both models across our 500+ domain portfolio—retainers for clients who want hands-off growth, and project engagements when they need a specific deliverable like migration support or a penalty recovery. The key difference between good and mediocre SEO services is whether the provider tracks real revenue or lead metrics instead of vanity rankings, and whether they adjust strategy when data says the initial hypothesis was wrong. Watch out for providers who promise page-one rankings in 30 days or sell packages with fixed keyword counts—that usually signals outdated tactics or link spam. Legitimate SEO takes 4–9 months to show measurable organic traffic growth, and the timeline stretches in competitive verticals like legal, finance, or SaaS.
