Free on-page SEO checks from pasted HTML or page content
WebToolsEdge SEO Analyzer is a free browser-based tool for reviewing pasted HTML or page content before publication. It checks title tags, meta descriptions, H1 headings, images and missing alt text, links and word count. An optional focus keyword enables keyword placement and density checks. The analyzer updates its report as content is entered and provides a score, recommendations and a copyable report. It analyzes the supplied content rather than crawling a live URL.
