Google truncates titles by rendered width, roughly 600 pixels on desktop, which works out somewhere around 50 to 60 characters depending on how wide your letters are. Descriptions get around 920 pixels on desktop and less on mobile. Front-load the specific detail in the first 120 characters so it survives truncation.
Since 2021 Google has rewritten titles it judges unhelpful or keyword-stuffed, often substituting the page h1. Write for the click, not for a pipe-separated keyword list. Descriptions duplicated across many pages are often replaced with text extracted from the body.
Optional Open Graph and Twitter tags use your dedicated fields or fall back to title and description. There is no meta keywords tag. Robots meta is emitted only when indexing or following is turned off — default index,follow adds no robots line. Attribute values are escaped so quotes in copy do not break your HTML.
That is the promise behind every tool here. Files are read in your browser tab, processed there, and discarded when you close it — never uploaded to our servers.
Approximate large-image and compact link cards plus copyable og/twitter meta — not a live platform fetch.
Build a urlset XML from a URL list with escaping, dedupe, and optional download — in your browser.
Compose robots.txt with Allow/Disallow lines, sitemap URL, and warnings for Disallow: /.
Append utm_source, utm_medium, and campaign params with lowercase hints — existing query params preserved.
Word and two-word phrase frequencies with optional stopwords — diagnostic, not a ranking target.
