On-page SEO auditing is the foundation of search engine optimization. It ensures that search engine crawlers can successfully find, understand, and display your pages in search results. Using our free SEO Analyzer, you can run a real-time audit of any live URL or raw HTML code to identify and fix critical ranking blockers.
The HTML title tag and meta description are the most prominent elements of your search engine listings. A well-optimized title tag should be between 50-60 characters (or under 580 pixels) and contain your target keyword near the beginning. The meta description, while not a direct ranking factor, acts as advertising copy for your page. Keep descriptions between 150-160 characters (or under 990 pixels) to prevent them from being truncated in search result pages.
Proper use of heading tags (H1 through H6) establishes a clear content hierarchy for search engine algorithms. Each page must contain exactly one H1 tag representing the primary topic of the page. Subsections should use H2 and H3 tags in sequential order. Avoid jumping straight from an H1 to an H3 or using headings for stylistic purposes rather than structure. A solid heading hierarchy makes it easier for search spiders to crawl and index your sections.
Search engine crawlers cannot "see" images the way humans do. Alt attributes (alternative text) explain the content of an image to crawlers and screen readers. Every image should have descriptive alt text that includes relevant keywords when appropriate. Additionally, links must be crawlable. Ensure all links have descriptive anchor text (avoid generic terms like "click here") and proper crawlable structures so search engine spiders can discover subpages.
A low score usually indicates critical ranking errors, such as a missing title tag, a duplicate H1 tag, missing image alt attributes, or broken internal links. Addressing these priority items will improve search engine accessibility.
A canonical tag (rel="canonical") tells search engines which version of a URL is the master copy. This prevents duplicate content issues that occur when a single page is accessible via multiple URL structures (e.g. HTTP vs. HTTPS, or with tracking parameters).
Our tool runs a server-side PHP proxy that fetches the HTML source code of the requested URL from the server rather than the client browser, completely bypassing cross-origin resource sharing (CORS) blocks.
No. A perfect SEO score indicates that your page is technically optimized and fully crawlable. However, actual search rankings depend on many other off-page factors, including content depth, authority backlinks, and user intent match.
