SEO Studio — Blog Post Optimizer

You wrote a good post. Then you published it with a truncated title, no keyword in the first paragraph, and three subheadings that say nothing.

That’s not a writing problem — it’s a checklist problem, and it quietly costs rankings you’d otherwise have earned.

SEO Studio is a single file you double-click. It opens in your browser, works completely offline, and checks your draft in real time as you type.

What it checks — 17 items across four groups:

• Keyword placement — title, URL slug, meta description, opening paragraph, and subheadings, plus whether you’ve used the phrase enough times without stuffing it
• Title & meta — exact character counts against what Google actually displays, and whether your title has a hook worth clicking
• Structure — word count, H1 count, number of sections, and paragraphs too long for mobile readers
• Readability — reading ease score and average sentence length

Plus:

• A real Google preview showing exactly how your title and description will appear in search — including where they get cut off
• Live stats — word count, keyword mentions, reading ease, estimated read time
• One-click copy for your title, meta description, or a full text report you can paste into your notes

Why not just use Yoast or RankMath? Those are WordPress plugins. This works on any draft, anywhere — Google Docs, Notion, Ghost, Squarespace, a client’s site, or a post you haven’t put into a CMS yet. It’s also honest about its limits: the guide states plainly that the score is a checklist, not a ranking prediction, and that it can’t assess your competition or backlinks.

• Single HTML file — Windows, Mac, Linux, and mobile browsers
• 2-page quick-start guide explaining what every check is looking for
• No plugin, no login, no subscription, no internet required
• Your draft never leaves your device
