Cron Generator
Build crontab schedules visually instead of recalling the field syntax.
Generate the core SEO meta tags for a page.
Produces the basic SEO tags — title, description, canonical and the OG/Twitter card set — in one copyable block.
It emits only the fields you fill in: `<title>`, description, keywords, canonical and the four `og:*` tags (title, description, url, image) — empty fields produce nothing rather than placeholder lines.
Three jobs are covered: **search-result basics** (title and description), **the canonical address** (which URL is the one to index when the same content lives at several), and **social share previews** (the four og tags).
The scope is deliberately narrow: no `twitter:*`, no `og:type` or `og:site_name`, no image dimensions — the **OG image** tool covers those properly, with previews for four platforms.
Fill the essentials
Title and description are the must-haves; canonical takes a full address including scheme and host.
Add an image URL for sharing
`og:image` must be absolute — a crawler cannot resolve a relative path.
Copy into <head>
The output is a continuous block of tags; paste the whole thing.
Not for ranking: Google has said since 2009 that it does not use the tag, and neither do the other major engines. Keeping it is for on-site search, CMSes and older systems that still parse it. What moves click-through is how the title and description read, not keyword stuffing.
Rules of thumb: **title up to 60 characters, description up to about 155** (roughly 600 pixels, beyond which the result is truncated with an ellipsis). Put the important words first, and write the description like ad copy rather than a keyword list — it is not guaranteed to be used, since engines often pull a snippet from the page instead.
