Read the full reviews: PageSpeed Insights and Yoast SEO.
Yoast SEO
Useful keyword and site-content insights, but not a full standalone SEO research suite.
Yoast says Premium analyzes up to five keyphrases and its free plugin integrates Semrush for expanded keyword research: https://yoast.com/wordpress/plugins/seo/ and https://yoast.com/product/yoast-seo-wordpress/
Keyword research quality for SEO content
Discovery
How well the tool identifies, qualifies, clusters, and prioritizes keywords specifically for SEO content creation.
PageSpeed Insights
No keyword discovery, volume, difficulty, intent, or keyword-management capability is shown.
The official homepage only offers URL analysis and does not present keyword research: https://pagespeed.web.dev/
Yoast SEO
Good in-editor keyphrase, synonym, word-form, and Semrush-assisted research; limited compared with dedicated research platforms.
The product page describes up-to-five-keyphrase analysis, synonyms and word forms, while the free product page names Semrush integration: https://yoast.com/wordpress/plugins/seo/ and https://yoast.com/product/yoast-seo-wordpress/
Content execution
Execution
How well the tool helps produce, optimize, or operationalize SEO content.
PageSpeed Insights
It diagnoses pages but does not create, edit, brief, or publish content.
The official report lists audits and opportunities, not content generation or publishing actions: https://pagespeed.web.dev/analysis/https-example-com/qx5m09i4ch?form_factor=mobile
Yoast SEO
Strong guided writing and AI drafting with review controls.
Yoast documents AI titles/meta descriptions, Content Planner starter drafts, readability feedback, and real-time fixes: https://yoast.com/wordpress/plugins/seo/
Context gathering
Grounding
How well the tool gathers the business, competitor, SEO, internal, third-party, and custom API context needed for differentiated recommendations and content.
PageSpeed Insights
No competitor, company, SEO-platform, third-party-app, or custom-API context gathering is documented.
The homepage provides a single URL input rather than contextual connectors: https://pagespeed.web.dev/
Yoast SEO
Uses the site’s own posts/pages for linking and planning context, but no broad business-context ingestion is documented.
The Content Planner draws five ideas from the user’s own site and internal-linking uses site posts/pages: https://yoast.com/wordpress/plugins/seo/ and https://yoast.com/features/internal-linking-suggestions/
AI-search / GEO
Visibility
How directly the tool helps teams improve visibility in AI answer engines and citation-oriented search journeys.
PageSpeed Insights
An Agentic Browsing audit is present, but the official page does not claim AI-search visibility, answer-engine optimization, or GEO research.
The report describes Agentic Browsing as browsability/WebMCP checks, not GEO: https://pagespeed.web.dev/analysis/https-example-com/qx5m09i4ch?form_factor=mobile
Yoast SEO
Schema aggregation, llms.txt, and AI-crawler controls directly support AI discovery, but Yoast does not document cross-engine citation tracking.
Yoast documents machine-readable schema, llms.txt, and controls for GPTBot, CCBot, and Google-Extended. https://yoast.com/features/schema-aggregation/ https://yoast.com/features/ai-features/
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.
PageSpeed Insights
No geographic or local-search targeting, localization workflow, or regional rank data is shown.
The official homepage contains no geographic targeting feature: https://pagespeed.web.dev/
Yoast SEO
Advanced AI-readiness features are present, including machine-readable schema and AI crawler governance.
Yoast calls structured data and Schema Aggregation AI-readiness features and says Bot Blocker controls GPTBot, CCBot, and Google-Extended: https://yoast.com/wordpress/plugins/seo/ and https://yoast.com/features/bot-blocker/
Technical SEO
Diagnostics
How strong the tool is for crawling, audits, indexability, metadata, status codes, and technical site health.
PageSpeed Insights
Useful page-level performance and SEO diagnostics, but not a site-wide crawler or issue-management system.
Official reports expose Core Web Vitals, Lighthouse audits, and page-level SEO checks: https://pagespeed.web.dev/
Yoast SEO
Very strong automated technical foundation for WordPress.
Yoast lists automatic XML sitemaps, schema markup, indexing controls, breadcrumbs, REST API, and technical foundations: https://yoast.com/product/yoast-seo-wordpress/
Publishing workflow
Operations
How well the tool moves work into CMS, publishing, approvals, or automated production workflows.
PageSpeed Insights
No editorial calendar, approvals, CMS publishing, or deployment workflow is shown.
The official product page offers Analyze and report views only: https://pagespeed.web.dev/
Yoast SEO
Supports editor feedback, bulk metadata work, redirects, and Google Docs export, with human approval.
Premium provides bulk metadata drafting with approval, redirects, and Google Docs publish-ready export: https://yoast.com/wordpress/plugins/seo/ and https://yoast.com/product/google-docs-addon/
Measurement & tracking
Measurement
How well the tool monitors rankings, content performance, visibility, or ongoing SEO progress.
PageSpeed Insights
Field data covers a rolling 28-day window and repeat tests support checks, without project-level rank or SEO tracking.
Official reports combine CrUX field data and Lighthouse lab diagnostics: https://pagespeed.web.dev/
Yoast SEO
Has rank-tracking and Google Site Kit/analytics connections, but limited native measurement detail is documented.
Yoast names Wincher for rank tracking and Google Analytics/Search Console data via Google Site Kit: https://yoast.com/product/yoast-seo-wordpress/
Team collaboration
Operations
How well the tool fits multi-person workflows, agencies, approvals, handoffs, and repeatable processes.
PageSpeed Insights
No teams, roles, comments, assignments, or shared workspace capability is shown.
The official homepage shows no collaboration controls: https://pagespeed.web.dev/
Yoast SEO
Google Docs enables contributors without CMS access and Premium includes one seat.
The add-on supports writers/freelancers without WordPress access and gives real-time SEO, readability, and inclusivity guidance: https://yoast.com/product/google-docs-addon/
Value accessibility
Buying
How easy it is for a team to reach value relative to pricing, setup complexity, and required expertise.
PageSpeed Insights
The public single-URL analyzer provides substantial value without a paid plan.
The official analyzer is publicly accessible at https://pagespeed.web.dev/
Yoast SEO
Core SEO is free forever; advanced automation is a relatively clear annual per-site purchase.
Yoast states the free plugin stays free forever and lists Premium at $118.80/year ex. VAT: https://yoast.com/product/yoast-seo-wordpress/ and https://yoast.com/wordpress/plugins/seo/
Free tools
Buying
How useful the tool is before payment through free tools, free plans, trials, or public utilities.
PageSpeed Insights
The complete PageSpeed Insights utility is available free on the public site.
The official analyzer is available at https://pagespeed.web.dev/
Yoast SEO
The free plugin is substantial, though Premium adds the main time-saving automation.
Free Yoast includes real-time analysis, XML sitemaps, schema, FAQ/How-To blocks, social previews, and integrations: https://yoast.com/product/yoast-seo-wordpress/
Estimated customer scale
Market proof
Estimated customer or user scale based on public claims, with source claims stored separately for auditability.
PageSpeed Insights
No customer, user, installation, revenue, or adoption count is published on the allowed pages.
The official homepage contains product links and workflow information but no customer-count claim: https://pagespeed.web.dev/
Yoast SEO
Yoast publishes a first-party installed-site figure.
The official product page says Yoast SEO is trusted by 13+ million sites: https://yoast.com/product/yoast-seo-wordpress/
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.
PageSpeed Insights
Machine-readable audits can feed automation, but PageSpeed Insights is not an autonomous SEO agent.
The official product returns audits and diagnostics rather than planning or executing SEO work: https://pagespeed.web.dev/
Yoast SEO
Machine-readable schema endpoints and llms.txt make the site consumable by AI agents, but autonomous agent operation is not documented.
Schema Aggregation adds a dedicated standards-based endpoint and Yoast AI features lists llms.txt: https://yoast.com/features/schema-aggregation/ and https://yoast.com/features/ai-features/
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.
PageSpeed Insights
Entering a URL produces an automated report with little setup, while prioritization and remediation remain external.
The official workflow is a single URL submission followed by diagnostics: https://pagespeed.web.dev/
Yoast SEO
Some drafting and automation reduce manual work, but human approval is intentionally required.
Yoast says AI drafts metadata and that users review every suggestion before it saves; redirects and link suggestions are assisted rather than fully autonomous: https://yoast.com/wordpress/plugins/seo/
