SEO is part science, part checklist. You can write amazing content, but if your meta tags are wrong, your Open Graph cards look broken, or Google truncates your title in search results, you're leaving traffic on the table. These five tools help you get the technical SEO basics right without paying for expensive software.

Meta Tag Generator

Every page on your website needs proper meta tags — a title tag, description, Open Graph tags for social sharing, and Twitter Card tags. Writing them by hand is tedious and error-prone. The meta tag generator creates them for you.

Enter your page title, description, URL, and an image URL. The tool generates the complete HTML block including <title>, <meta name="description">, all the og: tags, and Twitter-specific tags. Copy the HTML, paste it into your page's <head>, and you're done. No more guessing which tags you need or what format they should be in.

Open Graph Preview

You just published a blog post and shared it on LinkedIn. But the preview card shows the wrong image, a truncated title, and a description that cuts off mid-sentence. Embarrassing, and it tanks your click-through rate.

The Open Graph preview tool shows you exactly how your page will appear when shared on Facebook, LinkedIn, and Twitter — before you hit publish. Enter your OG data and see mockups of how each platform renders it. If the title is too long or the description gets cut off, you'll know immediately and can fix it.

Google SERP Preview

Your page ranks #3 on Google for an important keyword. But does the listing actually look good? Google displays roughly 60 characters of your title and 155 characters of your description. If your title gets truncated with "..." it looks incomplete and people click on the result below yours instead.

The SERP preview tool shows you exactly how your page will appear in Google search results — both desktop and mobile. It includes character counters so you can see when you're approaching the truncation point. Write your title and meta description with the preview updating in real time until it looks right.

Robots.txt Generator

Your robots.txt file tells search engines which parts of your site to crawl and which to ignore. Get it wrong and you might accidentally block Google from indexing your most important pages. Or you might let crawlers waste time on admin panels, staging environments, or duplicate content.

The robots.txt generator is a visual builder. Add user agents (Googlebot, Bingbot, or all crawlers), define allow and disallow rules, set a sitemap URL, and optionally add a crawl delay. The tool generates the correctly formatted robots.txt content that you can copy directly to your server's root directory.

No more syntax errors, no more wondering if you got the wildcard patterns right. The visual interface makes it obvious what each rule does.

Keyword Density Checker

You've written a 2,000-word article targeting the keyword "best running shoes." But how many times did you actually use it? Is 15 times too much (keyword stuffing) or is 3 times too few?

The keyword density checker analyzes your text and shows you word frequency, keyword density percentages, and even two-word phrases. It filters out stop words (the, a, is, etc.) so you see the meaningful keywords. Paste your article, scan the results, and adjust if any keyword appears unnaturally often or is conspicuously absent.

All five tools run in your browser with no data sent to any server. Your content stays private while you optimize it for search engines.
