SEO by Daniel vs Google Lighthouse

Google Lighthouse is the free audit that ships with Chrome. It scores one page on Performance, Accessibility, Best Practices, SEO and PWA, and it is the reference for front-end performance work. SEO by Daniel scores a site and produces a report. Lighthouse is a page instrument. SEO by Daniel is a site audit. That distinction decides which one you open.

Where Google Lighthouse wins

• It is free and open source. No account, no pricing, no limits. Run it as often as you like.
• Google maintains it. The audits track Chrome and Core Web Vitals, so the advice stays current.
• Per-page detail. You get LCP, CLS, total blocking time and a list of the exact resources slowing the page down. Nothing else at this price comes close.
• It runs where you work. Lighthouse lives in Chrome DevTools, the command line and CI, so a front-end developer never leaves the editor to run it.
• The score is understood. A 0-100 Lighthouse result needs no explanation in most teams.

Where SEO by Daniel wins

• It audits the whole site. One URL starts a crawl. Lighthouse scores the URL you give it and stops there.
• Sitemap auto-discovery. We read robots.txt, follow nested sitemap indexes and handle gzipped sitemaps, so the crawl finds pages you would not have pasted in by hand.
• It covers site-level SEO. Missing titles across a template, duplicate meta descriptions, redirect chains and thin pages. Lighthouse checks one page in isolation and cannot see the pattern.
• A client-ready report. Executive summary, issues grouped by severity and CSV export. Lighthouse gives you metrics a developer reads.
• Monitoring over time. We re-scan and track the score. Lighthouse is a check you run on demand.

A real example

You are a front-end developer shipping a redesigned landing page on a Laravel site. Before the deploy you run Lighthouse in Chrome DevTools. Performance is 61, mostly a hero image that is not compressed and a render-blocking script. You fix both, rerun, and get 94. That loop is exactly what Lighthouse is for, and no SEO tool replaces it.

The next morning the client emails to ask whether the rest of the site is okay. Lighthouse cannot answer that. You would have to open DevTools on every template, and even then it would not tell you that the blog pagination duplicates titles or that twenty old pages redirect through three hops. Those are site-wide findings.

So you run SEO by Daniel once on the domain. The crawl discovers the pages through the sitemap, the report groups the issues by severity, and you send the client the executive summary. You keep Lighthouse for the page you are building and SEO by Daniel for the site you are responsible for. They do different jobs well.

The verdict

| | Google Lighthouse | SEO by Daniel | |---|---|---| | Best for | Deep per-page performance work | Whole-site scored reports | | Scope | Single page | Full site crawl | | Cost | Free | Free scan, €19/mo entry | | Sitemap discovery | No | Automatic | | Catches template-wide issues | No | Yes | | Client-ready report | No | Executive summary, severity grouping, CSV | | Monitoring | On demand | On a schedule |

When to pick which

Pick Google Lighthouse when you are building or debugging a page and want the authoritative performance breakdown. It is free, it is fast and it tells a developer exactly what to change. Nothing here replaces it.

Pick SEO by Daniel when the question is about the whole site, or when the answer has to reach someone who is not a developer. If you need a scored report with an executive summary, or you want to know when a score drops, that is the other tool.

FAQ

Is Lighthouse free? Yes. It ships with Chrome and runs in DevTools, the command line and CI at no cost. SEO by Daniel's quick scan is also free with no account.

Can Lighthouse crawl a whole site? Lighthouse audits the single page you point it at. It is not a crawler, so it will not find duplicate titles or redirect chains across a site.

Do I need both? If you build pages and look after sites, probably. Use Lighthouse while you build and SEO by Daniel when you need a site-wide score and a report you can send.
