The verdict in three sentences
A B2B monthly SEO retainer should be chosen by growth ambition, not by lowest price. The 2026 grid runs in three tiers — CAD 900, 1,800 and 3,600/month — with a minimum six-month term. Over twelve months, a well-executed retainer targets a 3x to 5x ROI in pipeline value generated.
The three-tier grid
Each tier combines content production, link building and tracking. The difference is volume and acquisition aggressiveness.
| Tier | Price (CAD/month) | Content/month | Link building | Digital PR |
|---|---|---|---|---|
| Basic | 900 | 2 | no | no |
| Growth | 1,800 | 4 | yes (2 links) | no |
| Scale | 3,600 | 8 | yes (4-6 links) | yes |
| Custom | from 5,200 | 10+ | intensive | yes |
These rates are a 2026 order of magnitude for serious agency support. Below CAD 750/month, actual output is usually too thin to move positions.
Term and return on investment
Recurring SEO is a compounding asset: each piece of content and each link keeps producing after its creation month. Here is the typical trajectory.
| Horizon | Basic | Growth | Scale |
|---|---|---|---|
| 3 months | +10-15 % traffic | +20-30 % traffic | +30-45 % traffic |
| 6 months | +25 % traffic | +50 % traffic | +80 % traffic |
| 12 months | ROI 2x-3x | ROI 3x-4x | ROI 4x-5x |
| Leads/month added | 2-4 | 5-10 | 12-20 |
| Keywords in top 10 | 15-25 | 40-60 | 80-120 |
ROI depends on deal size: the higher it is, the faster Scale justifies itself. In high-value B2B, the premium retainer often pays back on a single signed contract.
Mini case study
David, sales director at an industrial SME in Toronto, subscribes to the Growth tier at CAD 1,800/month for twelve months, i.e. CAD 21,600. His average deal is CAD 27,000 with a 25 % close rate. Over a year, SEO brings 7 extra monthly leads at steady state, about 20 contracts on the year. Even attributing only a third of those to SEO, pipeline value exceeds CAD 150,000: the ROI is well above 5x.

FAQ
Why a six-month term?
SEO produces over time: indexed content, links gaining authority, reviews collected. A shorter term does not allow a real return to be measured.
What is the difference between Basic and Growth?
Basic maintains and grows slowly (2 pieces, no link building). Growth adds link building and doubles output, clearly accelerating positions on competitive queries.
Is link building really necessary?
In competitive markets, yes: content alone plateaus. Two to six quality links a month often make the difference on high-volume keywords.
Can I stop any time after the term?
Yes. Past the six months, the retainer is usually rolling, cancellable monthly. Gains remain, but progress slows without production.
How do I measure ROI?
By tracking leads attributed to organic and their close rate, then comparing pipeline value to the annual retainer cost.
