Free SEO tools to improve your website's search visibility

Search engine optimisation involves dozens of small technical tasks that need to be done correctly to help your pages rank well. Our free SEO tools handle the most common of these tasks — generating properly formatted meta tags, checking keyword usage in your content, creating robots.txt rules and building the HTML code you need for each page.

Meta Title Generator

A meta title is the blue heading text that appears in Google search results. It is the single most important on-page SEO element because it tells search engines and users what the page is about. The ideal meta title is 50–60 characters long, includes the primary keyword near the beginning and ends with the brand name. Our generator creates a properly formatted, length-checked title from any keyword or topic you enter.

Meta Description Generator

A meta description is the two-line summary shown below the title in search results. Although Google does not use it as a ranking factor, it directly affects click-through rate — a compelling description with the right keywords can increase organic traffic by 5–10% without any change in ranking. The ideal length is 150–160 characters. Our generator creates a concise, keyword-focused description for any topic.

Keyword Density Checker

Keyword density is the percentage of times a target keyword appears in relation to the total word count of a page. Historically, an overly high keyword density was considered keyword stuffing and could lead to penalties. Modern SEO best practice is to write naturally for readers first and check that the primary topic keywords appear at a reasonable frequency — typically 1–3% for the main keyword. Paste your content to see which words appear most frequently and at what density.

URL Slug Generator (for SEO)

Search engine-friendly URLs are short, lowercase, use hyphens as separators and include the primary keyword. A URL like /how-to-compress-images-for-website-free performs better than /page?id=2847 because it signals relevance to both users and search engines. Use the slug generator to create clean URLs from any page title or keyword phrase.
