Free Online SEO Tools
These are the small, unglamorous jobs that decide whether a page gets indexed properly: writing a title that survives truncation, generating a robots.txt that does not accidentally block your own CSS, checking how a link will look when someone shares it on LinkedIn. The tools here handle each of those without a trial period or a credit-card form. Character and word counters show live limits for titles, meta descriptions, and social posts. The Open Graph preview renders the actual card so you can catch a missing image before you publish, not after. The robots.txt generator writes valid directives with the crawl rules spelled out in comments, so the next person to open the file can tell what you meant.

Why use these seo tools
Live character limits
Title and meta description fields show the count against Google’s practical pixel limits as you type, so you know before publishing whether the tail of your description will be cut off.
Valid output, first try
The robots.txt and sitemap generators emit syntax that passes Search Console validation, including correct wildcard handling, sitemap declarations, and ISO-8601 lastmod dates.
See the share card first
The Open Graph preview renders Facebook, X, and LinkedIn variants side by side from your tags, catching missing images and truncated titles before the post goes out.
Frequently asked questions
How long should a title tag and meta description be?
Aim for roughly 50–60 characters for a title and 140–160 for a description. Google measures pixel width rather than characters, so wide letters shorten the usable count. The character counter and meta tag generator both show live counts against those ranges.
Will the generated robots.txt block my site by accident?
The generator defaults to allowing everything and makes each disallow rule explicit, with a preview of what the final file does. The classic mistake — blocking /assets or /static and hiding your CSS and JS from the crawler — is called out before you copy the result.
Can I use the sitemap generator for a large site?
Yes, within the 50,000-URL and 50 MB limits of the sitemap protocol. Past that, split into several sitemaps and reference them from a sitemap index. The tool runs in your browser, so there is no server-side cap on how many URLs you paste in.
