Do the company details on your pages match?
Compare company and brand information from up to five separate pages. Find different contact details and check prices with their respective context.
Select pages for matching
Structured company data, visible contact links, address fields, profile links and price sections are recognized. Free formulations are not fully understood. Differences between locations, products and tariffs must be assessed in context.
Their results
Example: Find an old phone number in the markup
Add the HTML and enter +49 30 1234 as a telephone reference. The example intentionally contains a different number.
<script type="application/ld+json">{"@context":"https://schema.org","@type":"Organization","name":"Beispiel GmbH","telephone":"+49 30 9999"}</script>Expected result
For the telephone reference appears “Manually check”. The proof cites +49 30 9999 as the found value and +49 30 1234 as the reference. If the telephone number is corrected accordingly, the reference comparison is “Found”.
What the Example Does Not Prove
A difference can also describe another location or point of contact. The tool does not confirm the real accessibility of the number or the legal identity of the company.
Checking contradictions with references
Each recognized item receives a source URL and a receipt. The comparison shall group similar information by field and recognizable company or product name. Deviations are test occasions, not automatically proven errors.
Prices need currency and period
19 euros monthly and 190 euros annually can both be right. Also, several locations or product variants are not automatically contradictory. Check the scope of services, billing period and timeliness together. Missing information in the HTML can be reloaded by JavaScript.
References help with matching
Optionally enter the confirmed name, address and telephone number. So you can see for each successful page whether this information occurs in the recognized fields. The check cannot confirm an official correctness or a knowledge graph entry.
Frequent questions
Does the tool check all pages of my website?
No. You can choose up to five URLs of the same host. Forwarded pages to another host are marked separately.
Is every deviation a mistake?
No. Locations, rates, companies and spellings may legitimately differ. Check the references before making a change.
Are there external API costs?
No. The check only loads the specified pages and analyzes their HTML. No language models or paid company databases are queried.
