Why G2 matters when you are hiring an SEO company
G2 built its reputation on software: buyers compare tools, leave reviews tied to a verified work identity, and the category grids are genuinely useful for that job. In January 2026 it acquired Capterra, consolidating two of the largest software review properties under one roof.
It matters for agency research because AI answer engines cite G2 heavily, and because if you are a software company hiring an SEO firm, your team already lives there. It is worth knowing what it does and does not tell you.
How to read an SEO firm on G2
- Check what is being reviewed. A G2 category may be reviewing a tool, a managed service, or both. Make sure you are comparing agencies to agencies.
- Reviewer identity is the strength. G2 ties reviews to a verified work profile, which makes them harder to fake than an anonymous star.
- Category grids are software-shaped. Leader and High Performer placement is built for products with feature sets and pricing tiers. It maps awkwardly onto services.
- Cross-check on an agency directory. If a firm is strong on G2 and invisible on Clutch, ask which business they are actually in.
Why a software directory reads differently
Software reviews describe a product that behaves the same for everyone. Agency reviews describe a relationship that behaves differently for every client. A five-star tool and a five-star agency are not the same claim, and a platform built for the first will always flatten the second.
That is not a criticism of G2. It is a reason to read agency reviews where they were designed to live, and to treat G2 as a supporting source rather than the deciding one.
G2 vs Clutch vs Google for SEO reviews
Clutch verifies agency reviews through client interviews that include budgets, which is the closest thing to proof in this category. G2 is stronger for software and for reviewer identity. Google is the broadest and most recent. For hiring an SEO firm, start with Clutch and Google, and use G2 as corroboration.
Common questions
Is G2 good for finding SEO companies?
G2 is built for software reviews rather than agency vetting, and it acquired Capterra in 2026. It is useful as a supporting source, especially if you are a software company, but agency directories like Clutch carry more relevant signal for hiring an SEO firm.
Is G2 the same as Capterra now?
G2 acquired Capterra in January 2026, so they are under one company. They still run as separate properties with different audiences, but treat them as related sources rather than two independent confirmations.
Where else should I check SEO reviews?
Google for volume and recency, Clutch for verified client interviews, UpCity or DesignRush for a marketing-specific view. If a firm looks strong in one place and nowhere else, that is worth a question.
