Frequently Asked Questions

What makes a technical seo agency the "best"?

The best technical seo agencies consistently earn high ratings across client satisfaction, delivery quality, communication, and value. On GoContento, rankings are built on verified client reviews, portfolio completeness, years of experience, and verified business status — not paid placements.

How are the best technical seo agencies ranked?

Rankings factor in average client rating, number of verified reviews, profile completeness (portfolio, services, team, case studies), GoContento Verified status, and years in business. No agency can purchase a higher ranking position.

How much do the best technical seo agencies charge?

Top technical seo agencies typically charge $2,000–$30,000+ per month for retainer engagements, or $5,000–$100,000+ for project-based work. Premium agencies command higher rates due to their track record, team expertise, and specialisation. Use the budget filter to find agencies within your range.

How do I evaluate a technical seo agency before hiring?

Review their GoContento profile: read verified client reviews, inspect their portfolio and case studies, check services and industry experience, look at team size and founding year, and compare their pricing range. Then request a proposal to start a conversation.

Are these rankings updated regularly?

Yes. Rankings update automatically as new client reviews are submitted, profiles are updated, and verification statuses change. The data shown reflects the current state of the GoContento directory.
