Keyword research quality for SEO content
Discovery
How well the tool identifies, qualifies, clusters, and prioritizes keywords specifically for SEO content creation.
AthenaHQ
Useful prompt-led query and volume intelligence, but the official product pages do not establish a conventional keyword database or keyword difficulty suite.
The Grüns case study says Athena's Prompt Planner identified high-monthly-search prompts using volume and mention intelligence across ChatGPT, Perplexity, and AI Overviews. https://athenahq.ai/case-studies/10-6pp-sov-gruns-ai-search-case-study
WebPageTest
No keyword discovery or keyword-volume workflow is documented.
The official product pages describe performance tests, Core Web Vitals, and diagnostics, but provide no keyword-research feature. https://www.webpagetest.org/
Content execution
Execution
How well the tool helps produce, optimize, or operationalize SEO content.
AthenaHQ
High: recommendations are paired with on-page/off-page actions, a content optimization agent, self-learning improvement, and Shopify publishing.
Starter lists on-page/off-page actions, content optimization agent, self-learning content improvement, and integrations; the case study documents programmatic content shipped with AthenaHQ Content and Shopify Integration. https://athenahq.ai/pricing https://athenahq.ai/case-studies/10-6pp-sov-gruns-ai-search-case-study
WebPageTest

AthenaHQ
Strong account and market context from competitors, citations, prompts, personas, regions, and a knowledge base/claim review layer.

WebPageTest
Grounded in detailed page-load, browser, network, device, and CrUX data, not business or broad SEO context.
Users configure browser, region, device, and connection for performance tests and can compare lab and field metrics. https://www.webpagetest.org/webvitals
AI-search / GEO
Visibility
How directly the tool helps teams improve visibility in AI answer engines and citation-oriented search journeys.
AthenaHQ
Core product focus: cross-platform AI visibility, recommendation coverage, citation analysis, and GEO/AEO actions.
The homepage explicitly lists cross-platform AI visibility tracking across 11+ LLMs, automated content optimization recommendations, and citation source analysis/link building. https://athenahq.ai/
WebPageTest
No generative-engine optimization feature is documented.
The official pages mention SEO rankings via Core Web Vitals but do not claim generative-search visibility, citation tracking, or AI-search optimization. https://www.webpagetest.org/
GEO readiness
Visibility
How ready the tool is for generative engine optimization: answer-engine visibility, citation likelihood, AI-search prompt surfaces, and content structures that AI systems can use.
AthenaHQ
Native AI-surface monitoring and controls make GEO readiness a primary capability.
The plans comparison includes dynamically managed smart robots.txt and llms.txt, brand voice/guideline enforcement, citation intelligence, and visibility across ChatGPT, AI Overviews, AI Mode, and other models. https://athenahq.ai/pricing
WebPageTest
No GEO capability in the generative-optimization sense.
The location capabilities are for performance testing geography, not generative-engine optimization. https://www.webpagetest.org/webvitals
Technical SEO
Diagnostics
How strong the tool is for crawling, audits, indexability, metadata, status codes, and technical site health.
AthenaHQ
Some technical AI-crawler and structured-content support is present, but the site does not document a broad technical SEO audit/crawl module.
The homepage FAQ recommends schema markup and crawler access, while pricing lists smart robots.txt and llms.txt management; no general crawl/audit feature is listed. https://athenahq.ai/ https://athenahq.ai/pricing
WebPageTest
Very strong Core Web Vitals and page-performance diagnostics.
The homepage explicitly connects WebPageTest to Core Web Vitals and SEO rankings; Tips also lists CrUX, Lighthouse, in-depth metrics, waterfalls, and API/integrations. https://www.webpagetest.org/tips.php
Publishing workflow
Operations
How well the tool moves work into CMS, publishing, approvals, or automated production workflows.
AthenaHQ
Strong action and publishing workflow with agents, integrations, exports, and human review evidence, though native CMS coverage is limited in the cited pages.

Measurement
How well the tool monitors rankings, content performance, visibility, or ongoing SEO progress.
AthenaHQ
Deep visibility, citation, sentiment, competitor, prompt, and revenue/traffic attribution measurement.

How well the tool fits multi-person workflows, agencies, approvals, handoffs, and repeatable processes.
AthenaHQ
Good team and enterprise collaboration controls through unlimited seats, RBAC, configurable views, SSO, audit logs, Slack, and enablement.
The pricing page lists unlimited seats/RBAC, configurable multi-views, Google/Microsoft OAuth, dedicated Slack, SAML SSO, audit logs, and white-glove setup. https://athenahq.ai/pricing

WebPageTest documents Pro team members, Slack result sharing, and GitHub pull-request comments. https://www.webpagetest.org/tips.php
Value accessibility
Buying
How easy it is for a team to reach value relative to pricing, setup complexity, and required expertise.
AthenaHQ
A meaningful free plan and transparent Starter price make entry accessible, although advanced scale and API use require paid or custom arrangements.
Essential is free with 300 credits; Starter is $295/month, while extra credits/API are add-ons and Enterprise is custom. https://athenahq.ai/pricing
WebPageTest
The core speed test is free and can run without an account.

Free tools
Buying
How useful the tool is before payment through free tools, free plans, trials, or public utilities.
AthenaHQ
The product has a free Essential tier and a free audit CTA, but the official pages do not show a separate catalog of standalone free SEO tools.
The pricing page lists Essential as Free with 300 credits and the homepage offers Get Free Audit (10m); no other free-tool catalog is shown on those pages. https://athenahq.ai/pricing https://athenahq.ai/
WebPageTest
Free tier includes substantial analysis rather than only a teaser.
Starter includes 150 monthly runs, Lighthouse, Opportunities, Filmstrip and Video, custom scripts, 30 locations, and Carbon Control. https://www.webpagetest.org/signup
Estimated customer scale
Market proof
Estimated customer or user scale based on public claims, with source claims stored separately for auditability.
AthenaHQ
The official industry page makes a substantial first-party scale claim, though it is a marketing-reported figure rather than independently verified here.
Athena's industry page states 2,400+ enterprise customers and 47 countries served. https://athenahq.ai/industry
WebPageTest
No numeric first-party customer count was found.
The homepage says it is trusted by top brands and shows logos, but does not state a numeric customer count. https://www.webpagetest.org/
Agent readiness level
Automation
How ready the product is to operate as or inside an AI agent workflow, based on tracked subcriteria for autonomy, controls, integrations, memory, and evaluation.
AthenaHQ
Agent-native features are central: Ask Athena, Athena AI agent, recommendation/content agents, and an Athena Citation Engine.
The homepage describes Ask Athena as an agentic copilot grounded in account data, and pricing lists Athena AI agent, content optimization agent, Recommendation Engine, and ACE. https://athenahq.ai/ https://athenahq.ai/pricing
WebPageTest
APIs, scripting, custom metrics, and CI automation make tests programmable, but no dedicated autonomous SEO agent is documented.

Ease of use and autonomous level
Automation
How easy it is for a team to reach useful outcomes, and how much work the product can perform autonomously after setup.
AthenaHQ
High assisted autonomy for diagnosis and recommended execution, with evidence of self-learning and largely self-running Enterprise workflows; human review remains relevant.
Starter advertises self-learning content improvement, while the Grüns customer says the Enterprise platform largely runs itself and describes human-in-the-loop proofreading. https://athenahq.ai/pricing https://athenahq.ai/case-studies/10-6pp-sov-gruns-ai-search-case-study
