Search work is easy to sell and hard to audit. The gap between a competent SEO agency and a convincing one is mostly visible in the questions they ask you, not the deck they show you.
The three workstreams
Almost all search engagements reduce to three areas, and most sites are limited by one of them.
- Technical: crawlability, indexation, site architecture, page performance, structured data, migrations. Often the binding constraint on large or recently rebuilt sites.
- Content: matching real search intent, topical depth, information quality, internal linking. Increasingly the constraint as answer engines summarise results.
- Authority: earning links and citations from sources that a search engine already trusts. The slowest workstream and the one most exposed to risky shortcuts.
Ask a prospective agency which of the three they believe is your constraint, before they have your analytics. A good answer is hedged but specific, and names what they would check first.
Questions worth asking
- What would you check in the first two weeks, and what would make you tell us not to hire you?
- How do you acquire links? Ask directly whether they buy placements, use private blog networks, or rely on guest posting at scale. Paid links that pass ranking signals violate Google's spam policies and put the site at risk.
- How do you approach AI overviews and answer engines? Look for work on entity clarity, structured data, source-worthy original information and clean crawlability, not a separate product bolted on.
- Who writes the content, and what is the subject-matter review process?
- What happens at the end of the contract? You should own the content, the tracking configuration and the documentation.
Deliverables that indicate substance
- A prioritised backlog with effort and expected impact, not a monthly list of completed tasks.
- Crawl and log-file analysis on larger sites.
- Content briefs that specify intent, entities and internal links.
- A staging environment review before any migration or redesign ships.
- Reporting that separates branded from non-branded search, and traffic from conversions.
Timelines and reporting
Meaningful movement on competitive terms typically takes two to three quarters, and technical fixes can show far sooner. Agree on leading indicators for the first quarter — crawl errors closed, pages indexed, briefs shipped, page performance — so that an early review is not purely a rankings argument.
Insist that reporting uses your own analytics and Search Console, shared directly with you, rather than a proprietary dashboard you cannot audit.
Warning signs
- Guaranteed rankings or a guaranteed position on a named term.
- A fixed monthly number of links or articles with no strategic rationale.
- Reluctance to explain how links are acquired.
- Reporting built on third-party visibility scores rather than your own data.
