Marketing tools
6 toolsThe small, fiddly jobs that sit between a campaign idea and a launch: tagging links so your analytics reads them correctly, seeing how your page will look when it is shared, counting the numbers behind ad spend and a split test, and turning a title into a clean URL. Each tool does one of them properly and shows its working, so you ship the campaign knowing the pieces are right rather than hoping they are.
All Marketing tools
Open Graph & Twitter Card Generator
Fill in a page's title, description, image and URL and get correctly escaped Open Graph and Twitter Card meta tags to paste straight into your head, alongside a live preview of exactly how the link will look when it is shared on Facebook, LinkedIn and X. The preview updates as you type, so you can fix a title that overflows or an image that crops before it goes live, and the built-in checks flag the mistakes, like a relative image URL, that silently break the card. Nothing is uploaded; the tags are built in your browser.
Open toolUTM Link Builder
Build a tagged campaign URL that tells Google Analytics, and every other analytics tool, exactly where a visit came from. Fill in the source, medium and campaign, watch the link build live, and get plain-language warnings for the small mistakes that quietly split your reporting. You can also paste an existing UTM link to decode it and see what it is really tracking. Nothing is uploaded.
Open toolSocial Media Character Counter
Write your post once and see the character count each platform will really apply, not a single generic number. It handles the rules that trip people up: X counts every link as 23 characters and doubles CJK characters, Instagram and LinkedIn cut your text off behind a 'more' link long before the hard limit, and each network caps hashtags differently. You get the live count, the remaining space, the exact point where the feed truncates, and counts of words, hashtags, mentions and emoji. Nothing is uploaded.
Open toolURL Slug Generator
Type a title and get a tidy, lowercase, URL-safe slug in real time: accented letters folded to plain ASCII, symbols and punctuation handled sensibly, spaces joined with hyphens, and an optional length cap that trims at a word boundary rather than mid-word. Preview the full URL, drop stop words to keep it keyword-focused, or paste a whole list of titles and slugify them all at once. It runs entirely in your browser; you sign in only to copy the result out.
Open toolAd Campaign Calculator
Enter what you already know about a campaign, the spend, impressions, clicks, conversions and revenue, and get every metric that matters worked out consistently: CPM, click-through rate, cost per click, conversion rate, cost per acquisition, ROAS, profit and ROI. Then read the plain-language funnel summary underneath, which points at the step that is leaking and tells you whether each sale earns more than it costs. Nothing is uploaded and nothing is stored; the maths runs entirely in your browser.
Open toolA/B Test Significance Calculator
Enter the visitors and conversions for your control and your variant and get a proper statistical read: each version's conversion rate, the absolute and relative lift, the p-value from a real two-proportion z-test, and a confidence interval on the difference. Instead of leaving you to interpret a p-value, the tool says in plain words whether the result is significant at the level you choose, and warns you when the sample is simply too small to trust. Everything runs in your browser.
