In-house SEO specialist or agency: which is better?

When a business starts thinking about search visibility, one of the first questions is who to hire: an in-house SEO specialist or an agency?

At first glance, having your own person on staff seems more reliable, more effective and “always at hand.” But look at the situation soberly, with numbers, and it becomes obvious: an agency wins in most cases, especially for small and medium-sized businesses.

Drawbacks of an in-house SEO specialist

  • High cost. A good SEO specialist's salary starts at 100,000 ₽. Add taxes — roughly another 50,000 ₽. Total: at least 150,000 ₽ a month.
  • Extra expenses. Tools, links, content, user-behavior signals — all of it is paid on top.
  • Narrow perspective. The specialist sees only 1–2 projects, which makes it hard to spot market trends.
  • Dependence on one person. Vacation, resignation, sick leave — and SEO grinds to a halt.
  • The illusion of activity. Often there is plenty of visible busyness that never turns into growth.
  • Hard to control. Objectively assessing the effectiveness of in-house SEO is difficult.
  • Conservatism. An internal specialist may stop learning and stop adopting new practices.

Advantages of an SEO agency

  • Better price. Project management from 70–90 thousand ₽ a month with tools included.
  • Team expertise. The project is run not by one person but by a team: SEO specialist, link builder, analyst and others.
  • Broad market view. An agency notices algorithm changes across dozens of projects.
  • Transparency and reporting. Work under contract, reports, KPIs, analytics.
  • Easy to replace. Not happy? You can switch contractors quickly.
  • Discipline and deadlines. Agencies work to a plan, without delays.
  • Backup. The project does not stop when someone goes on vacation or falls ill.

Conclusion

If you run a large, mature project, an in-house SEO specialist can make sense. But in most cases, for small and medium-sized businesses, an agency is the more cost-effective and efficient option.

The key is choosing the contractor wisely: one with case studies, transparency and a real stake in the result. Then SEO will actually work instead of imitating work.
