サイトを巡回して、切れたリンク、遅いページ、インデックスの問題を見つけ、順位が落ちる前に変化をつかみます。
These three do different jobs more than they compete. Google Search Console comes first because every site owner needs Google's own view of indexing and traffic, free. SiteOne Crawler is second for a full crawl of your own site, free on Mac, Windows and Linux. PageSpeed Insights is third for Core Web Vitals, one page at a time. Bing Webmaster Tools narrowly missed: it adds a site scan and Copilot citations, but for Bing only. Beam Us Up is also a free crawler, run by one developer. Screaming Frog and Sitebulb are ranked under SEO.
無料
Most site owners 向け
Google Search Console shows the clicks, impressions, positions and queries that bring people from Google, which pages are indexed and why others are not, Core Web Vitals, rich result and links reports, and email alerts about problems. It is free with a Google account, including URL Inspection, sitemaps, the API and up to 100 non-owner users per property. Know the limits: it covers Google only, nothing shows until you verify the site, it runs no crawl of your own, the API stops at 50,000 rows a day per search type, and the BigQuery export needs a billed Google Cloud project.
Google Search Console の料金と詳細無料
Anyone who wants a full-site audit for free 向け
SiteOne Crawler is a free, MIT-licensed crawler for Mac, Windows and Linux, as a desktop app or a single command-line binary. Each crawl ends in an HTML report scoring security, performance, SEO and accessibility from 0 to 10, covering tags, headings, redirects, 404s, security headers, SSL and caching, and it can fail CI builds or mirror a site. It is second because it shows nothing of how Google sees the site: it runs only on your own computer or server, with no hosted crawler or phone version, JavaScript sites need its optional browser mode, and AI help bills through your own API key.

Anyone checking page speed and Core Web Vitals 向け
PageSpeed Insights shows how real Chrome users experienced a page over the past 28 days, with a Core Web Vitals pass or fail, and runs a Lighthouse test on mobile and desktop with suggested fixes. It is free in a browser with no account, and its API works with or without a free key. It is third because it does a narrower job: one URL per run with no monitoring, no real-user data for pages with few Chrome visits, lab scores that vary from run to run, and shared reports that last 30 days.
