Robots.txt Generator

Meta Tag Generator writes a title tag, a meta description, an optional canonical link and always a robots meta line, from a title, a description, an optional canonical URL and index/follow toggles. Every value is HTML-escaped so a stray quote or angle bracket cannot break the markup. Character counters mark the title past 60 and the description past 160 — recommended lengths for readability, not a rule any search engine publishes or enforces. The search-result preview is a plain desktop-style block (URL, title, description); it does not trim to pixel width or show a mobile layout, favicon or rich result. It writes only these core tags: no Open Graph, Twitter Card, viewport, charset or keywords. It runs in the page and copies to the clipboard.

UTM Campaign URL Builder appends the five standard tracking parameters — utm_source and utm_medium (both required), plus optional utm_campaign, utm_term and utm_content — to a destination URL. It parses the URL with the browser's URL API, so any existing query parameters and the fragment are kept, and a utm_ parameter that is already on the URL is replaced rather than duplicated. Values are trimmed and percent-encoded by the URL API but are not lower-cased or otherwise normalised, so "Email" and "email" stay different — keep your own naming consistent. Only these five utm_ keys are added; there is no gclid, fbclid or custom parameter, and the link is never shortened or sent anywhere. An empty optional field is simply left out.

Open Graph Preview builds and previews the social metadata that platforms read when a page is shared. Fill in a title, description, page URL, image URL, site name and og:type (website or article), and the tool generates the Open Graph tags (og:title, og:description, og:url, og:type, og:image, og:site_name) and Twitter/X Card tags. twitter:card is always emitted, and twitter:title, twitter:description and twitter:image are generated from the Open Graph values unless you fill an override — your input fields are never changed for you. URLs are checked for the http:// or https:// scheme, and a script-like value is escaped, never executed. Two illustrative previews — wide and compact — show how a card can look; the image URL you enter is put in the tags but never fetched by Tooliba, so there is no preview image until you optionally drop a local one, which stays on your device and is not added to og:image. Character counts and guidance flag empty descriptions, missing images, http URLs and very long text without blocking generation. It does not reproduce Facebook, X or LinkedIn exactly, and it does not read metadata from any remote page. Unlike the Meta Tag Generator, which handles title, description and robots tags, this tool focuses on social metadata. Everything runs locally; nothing you type is sent anywhere.

Schema Markup Generator builds clean Schema.org JSON-LD from structured forms, entirely in your browser. Version 1 supports five deliberately focused types — Article, Organization, LocalBusiness, Product and FAQPage — rather than many shallow forms. Pick a type, fill the fields, and the tool validates what it produces: it separates fields that are Required to generate this schema from Recommended and Optional ones, checks that URLs use http:// or https://, that dates are real YYYY-MM-DD values, that a currency is a recognised ISO 4217 code and a price is a non-negative number, and that coordinates are numeric. An Offer is added to a Product only when both price and currency are given; Review and AggregateRating are never invented. You get two outputs: the raw JSON-LD, always valid and indented with two spaces, and a ready-to-paste <script type="application/ld+json"> snippet in which angle brackets are escaped so a value containing </script> cannot break out of the tag. Copy either one, or download a .jsonld file. Warnings flag missing recommended fields, http URLs, a modification date before the publication date, a Product with no offer or duplicate FAQ questions, without blocking generation. This tool checks the fields it generates and produces Schema.org JSON-LD; search engines apply their own eligibility and quality rules. It does not check Google rich-result eligibility, does not guarantee a rich result or indexing, and does not replace the Rich Results Test or the Schema Markup Validator. Unlike the Meta Tag Generator (title, description and robots tags), a hreflang generator (relationships between language versions) or an Open Graph preview (social sharing metadata), this tool produces Schema.org structured data as JSON-LD. Nothing you enter is sent anywhere.
