The title and main heading are in different scripts
In the reportTitle and H1 writing-system mismatch
title_h1_script_language_mismatch · Review item
This appears when a page's title and its main heading are written mainly in different scripts, for example a Latin title and a Greek H1. Google may choose a different title link when the title does not match the writing system of the page's content. Confirm both describe the same language version; brand names and multilingual titles can be intentional.
Severity: Low. Review it when convenient; the finding points to a possible mix-up between language versions.
Why it matters
Google says that when a page's title does not match the writing system or language of its primary content, it may choose a different text for the title link.
What to do
- Look at the finding: it shows the title, the heading and the script found in each.
- If the page is one language version, write its title in the same language as its content.
- If the mix is intended, such as a brand name, leave it.
When to leave it as it is: if the title holds a brand name or a deliberate second language, the mix is intended, and you can leave it.
What we read
We read the first <title> and the first <h1> with text in each page's HTML, without running JavaScript. We count characters in fixed Unicode ranges for Latin, Cyrillic, Greek, Hebrew, Arabic, Devanagari, Thai, Hiragana, Katakana, Han and Hangul; these ranges also hold some digits and signs, such as Arabic-Indic digits or ×. A text has a main script when it has at least four counted characters and one script makes up at least 70% of them.
A page is reported when the title and the heading both have a main script and the two differ. Languages that share a script, such as English and French, are not told apart, and a text with no main script is not compared. We check pages that answered 200 with HTML, carry no noindex and either declare no canonical or name themselves as canonical. Pages that are only a frame for scripts are left out; pages where scripts add part of the content are still compared.
Example & evidence
Illustrative example — one page's title and heading, not a live audit.
Address: https://bakery.example/rye-bread:
<title>Rye bread | Example Bakery</title>
<h1>Ψωμί σίκαλης</h1>The title is Latin and the heading Greek, so the page is reported with both texts.
A possible correction for a Greek page: <title>Ψωμί σίκαλης | Φούρνος</title>.
Confirm & check again
Check for yourself: compare the page's title in the page source with its main heading, and check that they are in the language the page is written for.
Check again: Full audit — run a new audit of the site. The finding closes when the page is read again as a complete HTML page and the two no longer differ in script, or one no longer has a main script. A page that now carries noindex, names another page as canonical or is only a frame for scripts cannot be confirmed. It can also close when the address answers directly with 200 and a file that is not HTML, or starts with a permanent redirect within your site.
Limits & sources
The check compares scripts, not languages, and uses only the first H1 with text, while Google compares the title with the page's main content. Letters outside the listed scripts, such as Armenian, Georgian or Vietnamese extended Latin, are ignored.
Confidence: Medium because a script difference is a sign, not proof, of a language mix-up.
