For a small or mid-sized business site whose problem is technical and structural, choose a one-time engineering pass. For a site in a competitive editorial market that needs a continuous stream of new content and links, choose a retainer with a provider who can show you what each month produced.
The two are not the same product sold on different billing terms. A one-time pass is a defined piece of engineering with a defined end. A retainer is an open-ended monthly service. Which one a site needs depends on whether its problem is something that gets fixed or something that has to be done continuously.
Unconventional Group sells SEO only as a one-time engineering pass, at $1,500 to $2,000, and does not sell a retainer.
Side by side
| One-time SEO pass (Unconventional Group) | Monthly retainer | |
|---|---|---|
| What it is | A defined engineering pass: crawlability, structure, internal linking, structured data, local search, mobile performance, baseline and handover. | An ongoing service; scope varies by provider. |
| Cost | $1,500–$2,000, fixed in writing before work starts. | A recurring monthly fee, set by the provider, for as long as the engagement runs. |
| What you own | The fixes are in your site. The handover document lists every change, why, and what to watch. | The work done is yours; the reports, tooling and sometimes the content licence may not be. Check the contract. |
| Who does the work | The people who scoped it. | Varies; often a mix of in-house and outsourced. |
| SEO / AEO structure | One page per query family, one canonical entity, structured data with real prices, redirect and canonical cleanup. AEO is a separate pass at $1,500–$2,000. | Depends on the provider. Technical work is often a one-off at the start, then content and links. |
| Measurement | A baseline captured before the pass; the same measurements re-run afterwards. | Usually a monthly report of rankings and traffic. Ask whether it is measured against a baseline. |
| Speed | Scoped and delivered as one piece of work. | Continuous; results accrue over months. |
| What happens when you leave | Nothing; the engineering stays fixed. | The content and link production stops. Confirm you keep everything produced. |
When a monthly retainer is the better choice
A retainer is the right call when the site's growth genuinely depends on continuous production: a publisher, a national e-commerce brand, or a business in a market where the competition is publishing weekly and building links every month. In that situation, one pass fixes the foundation and then the competition keeps moving. A good retainer provider shows you every month what was published, what was earned, and how the numbers moved against the baseline.
A retainer is also right when the business has no one internally to keep content current and wants that job outsourced entirely. Unconventional Group's own Growth Support plan at $349 a month is that kind of arrangement for sites it built: hosting, security updates, small edits, ongoing content, SEO upkeep and the $200-a-month AI visibility tracking subscription folded in.
When a one-time pass is the better choice
A one-time pass is the right call when the site's problem is engineering, which for most small and mid-sized business sites it is.
Crawlability, indexation, canonicals, redirect chains, sitemap and robots correctness are fixed once and stay fixed. Grouping pages so that one page answers each query family, and managing internal links as an asset, is done once and stays done. Structured data generated from one source so the price in the markup matches the price on the page does not drift. Core Web Vitals budgeted against a mid-tier Android phone (LCP under 2.5 seconds, CLS under 0.1, INP under 200 milliseconds) stay within budget until someone adds a heavy plugin. None of this needs to be billed monthly, and billing it monthly is how the industry ended up with retainers that produce a report instead of a result.
The pass ends with a handover document listing every change, why it was made and what to watch, and with the measured baseline captured before anything was touched. If the business then wants ongoing content or measurement, it makes that decision with the data in front of it, rather than at the start when nobody knows what the site actually needs.
What the pass will not do
It will not produce new articles every month, build links, or run advertising. It will not guarantee a ranking. Clients typically see movement in 14 to 90 days, measured against a baseline captured before the work starts; that is a typical-results claim, not a guarantee, and the range is wide because re-crawl, re-index and topic re-evaluation run on different clocks.
It also will not be sold to a site that does not need it. If a site is structurally sound, Unconventional Group takes the smaller job or none. If the platform cannot emit clean markup or the mobile performance cannot be fixed without a rebuild, the answer is a rebuild first, and the buyer hears that before paying.
