A search strategy engagement is bought when a business knows it should be doing better and does not know where to start. Its characteristic failure is a thorough, competent document listing several hundred recommendations that nobody prioritises, budgets for or ships. Avoiding that is less about the supplier's expertise than about what the deliverable is required to contain and who has agreed to act on it before the work starts.
A strategy is a sequence, not an inventory
The useful deliverable is a small number of ordered moves with an owner, an effort estimate and an expected effect, not an audit with hundreds of findings sorted by severity. Require prioritisation by expected value against effort, and require that the top items are specific enough for a developer or a writer to start on Monday without further interpretation.
It has to be built on what you can actually do
Recommendations that need a platform migration, a content team you do not have or approval from a department that will refuse are not strategy, they are a wish list. Brief the supplier on your real constraints, and expect the plan to name which items are blocked and what unblocking them would take. That naming is often the most valuable page in the document.
Include the measurement plan and the review date
Which queries and pages are being targeted, what the baseline is, where it is measured from, and when the plan is reviewed. Without that, the engagement ends with a document and no way to tell later whether it worked. Set the review date in the contract so that somebody is obliged to hold it.
Decide the execution question before you buy
Either the strategy is independent and you take it to whoever executes, or you are buying a combined engagement. Both are legitimate. What to avoid is a cheap strategy that turns out to be a sales process for a retainer, and a strategy from the firm that will implement it with nobody checking the scope it recommends.
Questions people ask about search engine optimization strategy services
How long should a strategy engagement take?
A few weeks for most sites: crawl and technical review, search demand analysis, competitor and results-page analysis, interviews with your team, and drafting. Much longer usually means the scope expanded; much shorter usually means the analysis is automated output with commentary.
What should it cost?
It scales with the size of the site and the depth of research. Ask for the fee split between analysis and writing, and check the analysis share is substantial. A large document assembled quickly from tool exports is cheap to produce and expensive to buy.
Is an audit the same as a strategy?
No. An audit says what is wrong; a strategy says what to do, in what order, with what expected return. Many engagements sold as strategy are audits with a summary, which is why the ordered-sequence requirement belongs in the brief.
Who should receive the deliverable?
The people who will act on it, and the person who controls the budget, in a session where they can argue with it. A document emailed to one marketing manager is the most reliable way to ensure nothing in it ever ships.
