Web and SEO tools
Generate UTM links, meta tags, Open Graph tags and robots.txt for your projects.
Tools in this category
This category's tools generate text and code -- URL parameters, HTML tags, robots.txt rules -- ready to copy. None of them query your actual website or check anything on the internet: generating a snippet isn't the same as publishing it, and publishing it isn't the same as a search engine automatically respecting it. This guide explains what each tool actually does and which steps remain your responsibility after generating the result.
What to prepare or check
Every tool in this category is a generator or text formatter: it takes the data you enter and produces a result (a URL, a block of HTML tags, a file's content) that you then copy and use where it belongs. None of this category's 6 tools makes a network request: they don't query your site, and they don't check whether a page exists, responds, or is indexed. If you need to check a URL's actual status (whether it responds, redirects, or is indexed by Google), this category doesn't offer that -- a separate checking tool is needed for that.
URLs, UTM campaigns and metadata
The UTM link generator adds tracking parameters (source, medium, campaign, term, content) to the end of a URL; those parameters alone don't track anything -- the outcome fully depends on the analytics configured at the destination (for example Google Analytics) actually reading them. The Meta Tags generator produces the basic page-head tags (title, description, robots, canonical) as text; generating them doesn't publish them: you have to insert them into your page's HTML yourself, and search engines aren't obligated to follow exactly what you put in robots or canonical -- they're signals, not guaranteed instructions.
Social preview and sharing
The Open Graph generator produces Open Graph and Twitter Card tags so a link shows an image, title and description when shared on social media. This tool doesn't preview how it will actually look on each social network: it generates the code, but each external platform caches, interprets, and sometimes trims that content its own way and on its own schedule, so the final result can vary depending on where the link is shared.
robots.txt: generating isn't controlling access
The robots.txt generator produces that file's content (crawl rules per user-agent and the sitemap reference) as text for you to upload to your domain's root -- generating it here doesn't publish or activate it. robots.txt isn't access control: it's a behavior request aimed at crawlers that choose to honor it, it doesn't stop anyone from visiting a URL directly, and it doesn't guarantee a crawl-blocked page stays out of a search engine's index (crawling and indexing are different concepts: a URL can still get indexed through other signals even with crawling blocked).
Minifying HTML and CSS: generating, not publishing
The HTML minifier and CSS minifier remove unnecessary whitespace, line breaks and comments from the code you paste, to reduce its size. They process the text you paste in your browser, without touching any file on your server or in your project: you have to copy the result and swap it in yourself wherever it belongs for the effect to show in production.
Privacy and limits
All 6 tools in this category process the text you enter in your own browser, without sending it to a server or querying any external URL. None of them check availability, HTTP status, redirects, real indexing status, or a page's security; every one of them generates text or code that you must install, publish, or swap in yourself for it to take effect.
Frequently asked questions
Does generating meta tags or robots.txt here automatically publish them on my site?
No. These tools generate the text; you have to copy it and publish it yourself on your site for it to take effect.
Do UTM parameters track anything by themselves?
No. They're just parameters added to the URL; tracking depends on the analytics configured at the destination actually reading them.
Does robots.txt control who can access my site?
No. It's a behavior request for crawlers that choose to honor it, not an access-control or security mechanism.
Does blocking a page in robots.txt guarantee it won't get indexed?
Not necessarily. Crawling and indexing are different concepts: a URL can still get indexed through other signals even with crawling blocked.
Does any tool in this category check whether my page responds or is indexed?
No. None of the 6 tools makes network requests; all of them generate text or code without querying your actual site.
Is the Open Graph preview I generate here identical to how it'll look on each social network?
Not necessarily. It generates the correct code, but each external platform caches and interprets that content its own way.
