Free tools

Four free tools, before any signup

The free read measures your page, its robots.txt and its sitemap, then renders SEO, GA4, Search Console and visual sitemap data. No account, no mail client.

SEO tables

Title and description lengths, canonical, robots meta, H1–H3 outline, word count, internal and external links, images without alt, JSON-LD blocks and types. Measured on the HTML you serve — never estimated.

free read · /api/free-read

GA4 report

Measurement IDs, dead Universal Analytics tags, container count, duplicated loaders, dataLayer and consent mode — everything that decides whether the sessions you report actually exist.

free read · /api/free-read

Search Console report

Verification tag, robots.txt directives, sitemap coverage and lastmod share, indexability, canonical host — what Google needs before it can index the page at all.

free read · /api/free-read

Visual sitemap

A SlickMap-style view of URLs declared in the XML sitemap, with page count, hierarchy depth, lastmod coverage and section distribution. It reads the sitemap; it does not invent traffic.

free read · sitemap analytics

Sessions and clicks need a connected property. Until one is connected, those two reports are labelled sample — nothing here is estimated silently.

The toolkit

Seven jobs behind the tables

Read-only by default, deterministic, covered by tests. Every answer arrives with the evidence behind it — including when the answer is no.

GEO audit

Score a page 0–100 across eight categories — robots, llms.txt, schema, meta, content, brand, signals, discovery — with the fix order computed from recoverable points.

geo_audit

Citability

A second score that asks whether a passage would be quoted: statistics, quotations, structure, question headings, answer-first writing, authorship, freshness.

geo_citability

llms.txt, generated and checked

Build the file from your sitemap, then catch drift after every deploy: links that left the sitemap, pages never added, and how many links still resolve.

geo_generate_llms_txt · geo_llms_drift

Structured data

Rich JSON-LD templates for WebSite, Organization, FAQ, Article, Product and LocalBusiness — five-plus attributes, not generic name-and-url markup.

geo_generate_schema

GTM installation

Verify the head loader, the noscript fallback, dataLayer order, default consent and duplicate containers — on staging before it reaches production.

gtm_audit_installation

IndexNow & Bing

Announce a changed URL to Bing, Yandex, Seznam and Naver in one POST — key file verified first, every response code explained. Google does not take part.

indexnow_submit · indexnow_verify

Positioning

Compare your page with named competitors: the vocabulary everyone shares, themes only you own, themes only they cover. Copy only — no traffic or ranking data.

geo_positioning

Analysis console

Every source in one place, and one decision out of it

Search Console, GA4, the GEO audit, citability and IndexNow, side by side. The console reads the sample audit of opendpe.net — the same payload the MCP tools return.

Measurement

GTM, measured end to end

Traffic you cannot see is traffic you cannot defend. The same server audits the container that produces the numbers.

Install

Page-level checks for the loader, noscript, dataLayer order and consent — plus a snippet generator that refuses malformed container IDs.

Inspect

GA4 configuration and event tags, triggers, variables, event parameters, duplicate tags and reverse lookups: what fires on a trigger, what uses a variable.

Prove

Cross-reference GTM events against events actually received in GA4, validate ecommerce payloads against the official schema, and gate the deploy on drift.

FAQ

The questions that decide the engagement

Is the free read a real audit?

Two layers. The URL score runs in your browser: HTTPS, hostname shape, path depth, tracking parameters, fragments, length, file extensions — that part never fetches anything. The SEO, GA4 and Search Console tables are measured server-side by /api/free-read, on the page, its robots.txt and its sitemap. When that API is not connected, the tables are labelled sample; npm run cli -- geo-free-read --url … gives the same rows locally.

What is GEO, and how is it different from SEO?

SEO optimises for a ranked list of links. GEO optimises for being quoted inside an answer: an engine has to fetch the page, parse it, resolve the entity and find a passage worth citing. They overlap — crawler access, structure, metadata — but a page can rank well and still be uncitable, which is why citability is scored separately here.

How long before AI engines cite me?

Nobody can promise a date, and any tool that does is guessing. What can be measured: whether crawlers are allowed, whether the entity resolves, whether a passage is quotable, and how fast a change is announced (IndexNow). The report gives you those, plus the projected score once the fixes ship.

Does this guarantee AI engines will cite me?

No, and any tool claiming that is guessing. The audit measures readiness: crawler access, llms.txt, structured data, citability, entity signals and discovery endpoints. It never queries ChatGPT, Claude or Perplexity, so it cannot claim an engine cites you.

Do you need access to my Google account?

Only for the GA4 and Tag Manager audits. Those use a service account invited to your properties with viewer access. Every write — tags, sitemaps, Indexing API, Measurement Protocol secrets — is disabled by default and requires a flag plus confirm=true.

What happens after I submit the form?

You get the full audit for the URL you entered, the three fixes with the highest recoverable points, and a short list of tracking gaps that would make the numbers unreliable. If it is not a fit, you still keep the audit.

Is it really open source?

Yes — Apache-2.0. The GEO rubric is adapted from the MIT-licensed geo-optimizer-skill model, credited in the docs. The server, CLI, site and tests are in the same repository.

Built on an MIT toolkit

Five GEO tools, one server, no reinvention

GeoSuite publishes a zero-dependency GEO toolkit under MIT. Three of its checks already existed here; the two missing ones are now native, so a single audit covers the whole set.

AI Crawl Check

Which AI crawlers robots.txt allows, per bot and tier.

native · geo_crawler_access

llms.txt Generator

Build the index from a sitemap, then catch drift.

native · geo_generate_llms_txt

Schema Templates

Copy-paste JSON-LD for six types, validated on the way out.

native · geo_generate_schema

Sitemap Builder

Crawl a site that ships without one, honouring robots.txt.
