What are the right title and description lengths?

Roughly 30–60 characters for a title and 70–155 for a description — that is what search results display before truncating. The preview shows the exact cut-off point for your text.

Does this check my live page?

No, and that is deliberate — there is no crawler and no account. You paste the title and description, and it measures and previews them locally.

Does the slug generator handle accents?

Yes — diacritics are folded, punctuation is dropped, stop words can be removed and the result is lowercase and hyphenated.

Meta Description Checker — Length, Preview and Keyword

Check a meta description against the length search results actually display, see the truncation preview, and confirm your keyword appears. No crawler, no account.
