SEO Tools
Free utilities to audit, fix, and grow your organic search presence.
Robots.txt Analyzer
Validate your robots.txt syntax, simulate crawler behavior, and catch directives blocking search engines.
.htaccess Tester
Paste your Apache rewrite rules and a URL — see the final URL, HTTP status, and per-line evaluation.
XML Sitemap Generator
Upload a CSV of URLs (with optional hreflang alternates) and download a ready-to-submit sitemap.xml.
RSS Feed Parser
Quickly extract URLs and published dates from any RSS or Atom feed.
Pre-rendering Tester
Compare what different crawlers see — fetch a URL with several user-agents and diff title, meta, H1, word count, canonical, and more.
Fetch & Render
Fetch and render a webpage as any bot. Get the raw source, the rendered DOM, a screenshot, and see which resources are blocked from crawling.
Mobile-First Index Tool
Compare the mobile and desktop versions of a page side-by-side and surface SEO, content, and structured-data discrepancies that put mobile-first indexing at risk.
hreflang Tags Tester
Validate hreflang annotations on a page (HTML + HTTP headers) or in an XML sitemap. Catches malformed codes, missing self-references, duplicates, and broken reciprocity.
Locale-Adaptive Tester
Fetch a URL with different Accept-Language values and see whether the same URL serves different content per locale — and whether Vary: Accept-Language is set.
Review Link Generator
Generate Google review shortcut links in bulk. Paste business names, one per line, and copy the resulting URLs to share with your customers.
SERP Simulator
Preview how your title and meta description will look in Google search. Fetches metadata from any URL, lets you tweak copy, toggle device, and download the preview as an image.

Browse every confirmed and unconfirmed Google algorithm update with dates, categories, and references. Updated frequently and filterable by year, category, and status.
Schema Markup Generator
Generate Schema.org JSON-LD markup for FAQ, Breadcrumb, Article, Product, LocalBusiness, Event, Organization, Person, Recipe, and How-To. Copy as JSON or as a ready-to-paste <script> tag.
