Key takeaway

Every agency on SEOCompare is scored against 12 weighted criteria totalling 100%. We publish limitations and weaknesses alongside strengths because readers making a purchasing decision deserve the full picture.

How we evaluate AI search agencies - 12 criteria framework

Why we built a structured framework

Most comparison sites score agencies on vague criteria like "reputation" or "quality." That tells you nothing when you are choosing between three agencies and need to justify the spend to your board. We built a framework that measures what matters for AI search visibility.

Every criterion has a fixed weight, a defined scoring rubric, and evidence requirements. We apply the same framework to every agency. One-person consultancy or 200-person firm. The full methodology is on our methodology page.

The 12 criteria and their weights

CriterionWeightWhat we assess
AI platform coverage15%Which AI engines they actively optimise for: ChatGPT, Gemini, Perplexity, Claude, AI Overviews, Copilot
Methodology transparency12%Whether their process is documented and publicly available, not hidden behind a sales call
Case studies with data10%Published case studies with measurable outcomes, not just client logos
Team expertise10%Named team members with verifiable backgrounds in AI, search, or technical SEO
Independent review scores10%Ratings on Google, Clutch, G2, and Trustpilot with sufficient volume to be meaningful
Pricing transparency8%Whether pricing is published or at least available on request without a lengthy sales process
Schema implementation8%Capability with structured data: FAQ, HowTo, Article, Speakable, and custom schema types
Content strategy7%Approach to creating AI-optimised content, including answer-first formatting and entity clarity
Industry focus5%Specialisation in specific verticals, particularly regulated sectors like healthcare and financial services
Reporting and measurement5%How they track AI citations, brand mentions, and visibility across platforms
Contract terms5%Minimum commitment length, break clauses, and flexibility
Bing optimisation5%Whether they actively optimise for Bing, which feeds ChatGPT and Copilot

Why AI platform coverage gets the highest weight

An agency that only optimises for Google is not doing AI search optimisation. ChatGPT sources from Bing. Gemini has its own index. Perplexity crawls independently. If an agency cannot explain their approach to each platform, they are selling traditional SEO with a new label.

Why Bing optimisation matters at 5%

Bing feeds both ChatGPT and Microsoft Copilot. Despite this, many agencies ignore it. We check whether agencies submit to Bing Webmaster Tools, use IndexNow, and track Bing rankings alongside Google. Five percent may seem small. But it reliably separates genuine AI search agencies from rebranded SEO firms.

Why we publish limitations

Every review on SEOCompare includes a "Limitations" section. No agency is perfect for every business. A firm that excels at enterprise B2B may be wrong for a local business. An agency with deep healthcare expertise may not understand ecommerce. Publishing limitations is not criticism. It is honesty that helps readers find the right fit.
