Free Online SEO Tools
On-page SEO comes down to a handful of things you can actually check: does the page have a sensible title and description, does it share properly on social, are the headings in order, does the sitemap parse, and is the URL readable. These tools each answer one of those questions and hand you the markup or the fix.
