SEO Tools — robots.txt, Sitemap, On-Page SEO Checker and SERP Preview
Generate and test robots.txt, validate XML sitemaps, check a page's title, description, canonical and hreflang, and preview how it looks in Google and Baidu results.
- Robots.txt Generator & Tester Generate: choose the paths to block, the crawlers to keep out and your sitemap URLs, and get a robots.txt ready to upload.
- XML Sitemap Checker Check your sitemap before submitting it — whether the XML parses, URLs are absolute, there are duplicates or other-host URLs, lastmod is well-formed and hreflang links point to each other.
- On-Page SEO Checker Enter any page URL to check the tags search engines care about most — title and description length, an accidental noindex, where the canonical points, how many H1s there are and whether hreflang includes the page itself — and preview the page in Google results.
- SERP Preview Preview your title tag and meta description as you write them.
- Access Log Analyzer Drop your server's access.log here to see within seconds which pages are popular, which URLs return 404 and which IPs hit you hardest.
- Crawler IP Verifier Scrapers often pretend to be Googlebot in their user agent.
- UTM Builder Tag the links in your newsletter, ads and social posts so analytics shows exactly which campaign brought each visitor.
- Schema Markup Generator (JSON-LD) Structured data tells search engines what a page is about — a product with its price, an article with its author and date, a shop with its address and opening hours.
- 301 Redirect Generator Moving to a new site structure or a new domain?
- XML Sitemap Generator Have a list of pages from your CMS, a spreadsheet or a crawl?
- llms.txt Generator llms.txt is a proposed standard file that gives AI assistants and LLM-based tools a short, Markdown guide to your site — what it is and which pages matter most.
