Standards & sources
Every check maps to public documentation
Our tools don’t invent scoring rules. These are the official specifications and guidelines they are built against:
- Google Search Central
Google’s own crawling, indexing and ranking documentation — the basis of our audit, meta and indexability checks.
- web.dev — Core Web Vitals
The LCP, INP and CLS thresholds our performance and page speed tools measure against.
- Schema.org
The structured-data vocabulary our schema generators emit and our validators check.
- Google rich results gallery
The rich result types Google actually supports, and the required properties for each.
- RFC 9309 — Robots Exclusion Protocol
The IETF standard that defines robots.txt parsing — how our robots and crawlability checks read your rules.
- IndexNow protocol
The open submission protocol we use to push new and updated URLs to search engines instantly.
- MDN — HTTP reference
The HTTP header, status code and redirect reference behind our technical and security checks.
From the practitioners
What our specialists tell every client
Three people, three angles on the same job — technical health, search intent and AI visibility.
“Most sites don’t have a ranking problem, they have a crawling problem. Fix indexability first and half of the ‘Google hates us’ symptoms disappear on their own.”
Yusuf DİNÇER
Technical SEO & Web Performance Lead
“A page ranks when it answers the exact question someone typed. Get the intent behind the keyword right and on-page optimization becomes the easy part.”

Common questions
Frequently asked questions about SeoMods
Short, direct answers to what people ask before running their first tool.
Are the SEO tools on SeoMods really free?
Yes — all 80+ tools are free, with no trial period, no paywall and no daily limit. No credit card is required. An account is optional and only saves your run history.
Do I need an account to run a tool?
No. Every tool runs instantly for anonymous visitors: paste a URL, domain or keyword, press run, and the report appears in seconds.
Where does the data in each report come from?
Each tool fetches the live target itself — the real HTML of the page, real DNS and WHOIS records, the actual SSL certificate chain and real Google Autocomplete. The few metrics that cannot be sourced for free are labelled as estimates.
Which tool should I start with?
Start with the On-Page SEO Audit for a scored breakdown of one page, or the All-in-One Audit when you want every check run against a single URL at once. Both return a prioritized list of fixes.
Can I use SeoMods in Turkish?
Yes. The entire site — every tool, every report and the whole blog — is available in Turkish under seomods.com/tr with localized URLs.
How is SeoMods different from Semrush or Ahrefs?
Those are paid platforms built for large-scale rank tracking and historical backlink databases. SeoMods covers the everyday checks — audits, lookups, keyword ideas and SERP previews — free and without a login.
