GEO

Synthesised by AI

The source Google AI Overviews and Gemini build their answer from.

One shared foundation: crawlable, structured, trustworthy content — run as a single program.

GEO isn't magic, and a capable team can do much of it in-house. The question is whether you have the people and the time for every part of it, especially the off-site work that takes the most effort. Here's how to think it through.

The skills GEO needs

SkillUsually in-house?
Technical checks: crawlers, schema, renderingOften, if you have a web developer
Answer-first writingOften, with some training
Keeping company facts consistentYes, with an owner
Reviews, directories and article outreachRarely done well in-house
Weekly prompt tracking across assistantsPossible with a tool and discipline

When in-house works

  • You already have a content team and a web developer with spare capacity.
  • Someone senior can own the program and protect time for it.
  • You're in a narrow niche where your people know the sources better than any agency.

When an agency works better

  • Nobody has time for steady off-site work, week after week.
  • You need results across several markets or product lines.
  • You want an outside view of what assistants say about you, without internal bias.

The hybrid most teams choose

In practice, many companies keep writing and technical work in-house and bring in outside help for strategy, measurement and off-site outreach. A GEO consultant can set the plan and review your team's work. An agency can take on the parts your team can't.

Count the full cost

In-house isn't free. Add up the hours for writing, technical fixes, outreach and weekly tracking, plus any tools. Compare that honestly with an agency fee. Many teams find the in-house version stalls on the off-site work, which is the part that moves AI recommendations most.

A rough time budget for in-house

WorkHours a month, roughly
Weekly prompt checks and logging4 to 6
Writing or rewriting key pages8 to 16
Technical fixes and structured data2 to 6
Review requests and directory profiles4 to 8
Article and list outreach6 to 12

For a small program that's roughly 25 to 50 hours a month. If nobody can protect that time, the off-site rows are usually the first to slip, and they matter most.

Frequently asked questions

Can I do GEO myself?
Much of it, yes: crawler checks, structured data, answer-first writing and tracking. The off-site work, such as reviews and article outreach, is where in-house programs often stall.
Is a GEO consultant cheaper than an agency?
Usually, because a consultant sets direction and reviews work while your team does it. It suits companies with writers and developers already in place.
What's the biggest in-house mistake?
Doing only on-site work. Without third-party mentions, AI recommendations rarely move much.
