Paying for SEO every month is easy to understand. Knowing what you are buying should be just as clear. An SEO retainer is an ongoing agreement for a defined scope of search engine optimization work. Before comparing fees, ask who will do the work, what they will deliver, and how you will decide what happens next.
We recommend a simple test: Scope, Ship, Verify. Define the work, identify who will implement it, and agree on the evidence you will review. A recurring invoice is not the plan. The plan should connect your search priorities to decisions your team can act on.
A retainer is not automatically the right starting point. You may need a defined technical project, an independent audit, or advice your own team can implement. Start with the work and the people available to do it.
Use these examples to compare delivery models. They are evaluation categories, not Selworthy service packages or contract terms.
| Model | Consider it when | Confirm before committing |
|---|---|---|
| Advice with client-led execution | Your team can implement changes but needs diagnosis, prioritization, or technical guidance. | Who owns implementation, how questions are handled, and whether follow-up verification is included. |
| Defined SEO project | You have a bounded task, such as a migration review, an audit, or a specified group of page repairs. | The deliverables, acceptance criteria, dependencies, and any support after handover. |
| Ongoing SEO retainer | You have recurring search and content work that needs prioritization, execution, and review. | The included scope or capacity, implementation responsibilities, review cadence, and rules for changing priorities. |
An audit can be a useful first project. Before buying ongoing work, ask whether its recommendations will be implemented by your team, the SEO provider, or a separate developer. An unassigned recommendation is not an implementation plan.
Ask the provider to explain how its proposed SEO strategy fits your products, services, audience, and current site. Then translate the scope into work you can recognize when it is delivered.
Treat these as recommended evaluation criteria, not a requirement to buy every activity every month. Set the review cadence around the agreed scope, site changes, and unresolved issues. Do not commission a full audit repeatedly without a clear reason.
We recommend comparing proposals only after you can explain the difference in what they include. A lower fee is not a useful comparison if one proposal includes implementation and another stops at recommendations.
Ask each provider to separate the recurring scope from setup work and optional projects. Check what happens when urgent work displaces a planned task. If the retainer buys a set amount of capacity, ask what consumes it, how usage is reported, and whether unused capacity carries over.
These are commercial evaluation questions, not legal advice. This guide does not set a market-average price or quote Selworthy pricing. Request a proposal for the work your business actually needs.
Before work starts, decide who can edit, who can approve, and who can publish. Ask how existing drafts and backups are protected. Give each proposed change an owner and make unresolved dependencies visible.
We recommend reviewing a small, defined set of changes through the full process before expanding the workload. For a page refresh, that means checking the source claims, title and description, links, images, mobile layout, and live result. For a technical repair, agree on the test that will demonstrate the intended behavior.
Keep link acquisition within the same review process. Ask how a proposed mention or link serves the audience, rather than buying a count. Google's link-spam policy addresses links created primarily to manipulate rankings, including paid ranking links and certain manipulative guest-post or forum placements. Advertising and sponsorship links have separate qualification requirements. The activity and its purpose matter; a guest article is not automatically a policy violation.
A report should help you decide what to do next. We recommend separating evidence of completed work from evidence of business impact.
For delivery, review the agreed changes, publication dates, verification results, and unresolved items. For outcomes, define the search and business measures before interpreting them. If you need to connect inquiries to later sales activity, agree on the analytics and attribution work rather than assuming every report already contains it.
Google Search Console's Performance report provides clicks, impressions, click-through rate, and average position, with dimensions such as queries and pages. Use comparable date ranges and consistent filters. State what the report includes before treating a change as progress or decline.
Use engagement metrics carefully. In GA4, bounce rate is the percentage of sessions that were not engaged, not simply the percentage of visitors who viewed one page. An engaged session can qualify through duration, a key event, or multiple page or screen views. See Google's current GA4 definitions. We recommend treating engagement as context for investigation, not a verdict on a page by itself.
A delivery date and a search-result change are different commitments. Ask when the provider expects to implement the work, what it will inspect afterward, and when you will review the evidence together.
Google's SEO Starter Guide says changes can take from hours to several months to appear in search results, and not every change produces a noticeable effect. That is not a promise of traffic, leads, or revenue within a standard retainer period.
Do not use that uncertainty to excuse missing work. You can ask for clear delivery evidence even while search outcomes remain unsettled. Equally, do not treat a short reporting window as proof that an implemented change caused a gain or loss.
When evaluating a provider, ask for its methods, relevant references, measurement approach, and explanation of proposed changes. Google's guidance on hiring an SEO recommends questioning providers and warns against guaranteed top rankings. We recommend a partner who can explain its work without asking you to accept a promise that no one can verify in advance.
Before signing, walk through a proposed page refresh and a technical issue. Ask who chooses the priority, supplies missing information, approves the work, implements it, and checks the result. If an answer is unclear, resolve it in the scope.
You may decide that a defined project is enough. You may need ongoing help. Our position is the same in either case: buy work you can understand and verify, with expectations that match the evidence.
