Most "free" SEO tools aren't actually free. They require an email address, force you to create an account, then limit you to 3 searches per day before showing a paywall. Ahrefs free tier? Account required, 10 searches. SEMrush? Account required, 10 searches. Moz? Account required, 3 searches.
Here are the SEO tools that actually respect your time: no signup, no email, no credit card, no limits. You open the page and use the tool. That's it.
SPUNK.CODES has the largest collection of free, no-signup developer and SEO tools on the web. Here are the SEO-specific tools that will save you hours and hundreds of dollars per year.
Generate perfect title tags, meta descriptions, Open Graph tags, and Twitter Card markup. Just enter your page details and copy the HTML. No Yoast plugin needed, no WordPress dependency.
Replaces: Yoast SEO ($99/yr), RankMath Pro ($59/yr)
Create XML sitemaps for your website instantly. Enter your URLs, configure priorities and change frequencies, download the sitemap.xml file. Submit it to Google Search Console and you're done.
Replaces: XML-Sitemaps.com (limited free tier), Screaming Frog ($259/yr for full)
Paste your content and instantly see keyword density, word count, reading level, and keyword distribution. Optimize your content before publishing instead of guessing.
