Tags, sitemaps, robots.txt, share cards and campaign links, checked before they ship
Everything here runs in your browser. Files are never uploaded.The parts of search that a developer actually controls are small, finite and easy to get wrong in silence: the title and description a result shows, the picture that appears when the link is pasted into a chat, the file that tells crawlers what to skip, and the sitemap that tells them what exists. These build each of those and show you the result before it goes live, rather than after somebody reports it.
Meta Tag Generator writes the title, description, canonical, Open Graph and Twitter tags together, with a live preview, so you can see a title truncate at around 60 characters instead of discovering it in Search Console. Keep descriptions under about 155 characters and make every page's pair different: two pages with the same description are competing with each other.
Open Graph Preview renders the card as Facebook, LinkedIn, X, WhatsApp and Slack each build it, which is worth doing once per template. They disagree about image sizes and about which tag wins, and the first time most teams find out is when a launch post shows a blank rectangle.
Robots.txt Generator builds the file from presets and then explains what each line really does, including the two rules people get backwards: a disallowed page can still appear in results if other sites link to it, and disallowing a page prevents crawling rather than indexing. Sitemap Generator turns a list of URLs into a valid sitemap.xml, and splits it into an index once it grows past the limit.
Slug Generator makes clean URLs from titles, including accented and Hindi text, one or a few hundred at a time. Favicon Generator produces the .ico plus the Apple and Android icons from one image. Keyword Density and Readability counts words and phrases and scores how hard a page is to read, which is a better use of it than chasing a density number.
UTM Builder tags campaign links consistently and exports the set as CSV. Consistency is the whole value: Newsletter, newsletter and news-letter are three sources in every analytics report ever built, and the report is useless before anyone notices.
None of these tools makes a page rank. They stop the avoidable failures: the missing description, the broken card, the sitemap with dead URLs, the robots rule that blocked the wrong directory. The rest is the content.
Around 60 characters for a title and 155 for a description, because that is roughly where a result gets cut off. Longer is not penalised; the part past the cut is simply not shown to anyone.
No. It stops a page being crawled. A disallowed URL can still appear in results, without a description, if other pages link to it. To keep a page out of results use a noindex tag, which requires the page to be crawlable.
Usually a missing og:image, an image behind a login, or one too small for the network. Each platform has its own minimum and its own cache, so preview the card, fix the tag, then ask the platform to re-fetch it.
50,000 URLs or 50 MB uncompressed, whichever comes first. Past that you need several sitemaps and a sitemap index, which the generator creates automatically.
None. Density stopped being a ranking signal long ago, and writing to hit a percentage produces text people leave. Use the count to spot a word you have repeated twenty times by accident, and the readability score to find sentences nobody can follow.
Yes, with no account. They all run in your browser, so the URLs and copy you are working on are not uploaded anywhere.
