For Founders, Marketing leads, In-house SEO · Intermediate · Commercial · Solves: Paying for blogs while indexation is broken, Unsure who to hire, Agency reporting without fixes
Key takeaways
- Consultants fix systems. Agencies run programs.
- Buy content only after the templates can support it.
- Interview people on your live coverage report.
- Hybrid works: specialist first, production second.
A technical SEO consultant and an SEO agency can both be useful. They are not interchangeable. Growing companies waste a year when they buy a content retainer to solve a crawl and architecture problem.
The search results for 'technical SEO consultant' are full of agency service pages. That is the market talking. Buyers still need a way to tell whether they need a specialist or a machine that produces blogs.
What a technical SEO consultant actually does
They inspect how search engines fetch, render, index, and consolidate your URLs. They tell you which templates leak duplicates, which JavaScript shells hide copy, which environments are indexed, and which migrations will erase the wrong slugs. They write a plan other people can implement.
They do not need to write 16 blog posts a month to be valuable. If that is the pitch, you are talking to a content shop.
What a typical SEO agency is built to do
Agencies are good at programs: content, digital PR, reporting, and coordination across several channels. The good ones have technical people. Many bury that person under an account manager and a dashboard. You get slides. The robots.txt stays wrong.
Choose a consultant when
- You are about to redesign, migrate, or change domains.
- Indexation in Search Console does not match reality.
- JavaScript rendering or faceted navigation is in play.
- You already have writers and need the site to stop fighting them.
- You want one adult in the room for a quarter, not a 12-month blog package.
Choose an agency when
- The technical baseline is healthy.
- You need production capacity: content, outreach, creative.
- You want a team that can attend the weekly marketing meeting.
- You have internal implementers who can take tickets from the SEO lead.
The hybrid that actually works
A consultant sets the system. An agency or in-house team executes content on top of it. Reverse that order and you scale pages that cannot be indexed cleanly.
Do not buy 40 articles for a site that canonicalizes them to the wrong template.
How to interview either one
- Ask them to explain your current indexation report live.
- Ask what they would not do in the first 90 days.
- Ask who implements redirects and schema: them, you, or 'the devs' as a blob.
- Ask for a migration they stayed with after launch, not only a pretty audit PDF.
If you are already heading into a rebuild, start with the technical SEO audit checklist so the conversation is about artifacts, not vibes.
What I will and will not pretend to be
I do technical, design, and implementation work on marketing sites. I am not a 20-person content agency. If you need a factory, hire one after the site can support it. If you need someone who will also implement the canonical and the schema, that is closer to how I work.
If you are stuck between a retainer and a specialist, send the Search Console coverage screenshot. That picture usually picks for you.
Implementation table
| Fix | Problem | What to change | Metric | Tool |
|---|---|---|---|---|
| Role split | One retainer for all SEO | Technical sprint, then content program | Issues closed vs posts shipped | GSC + tracker |
| Live teardown | Generic pitch | Interview on your coverage report | Specific issues named | Search Console |
