I tried analyzing my site's SEO using different online tools and they gave different results. Seoworkers.com result Title - The Title meta tag contains 68 characters with no errors. The Title relevancy to page content is 91%, which is very good. Description - The Description meta tag contains 130 characters with no errors. The Description relevancy to page content is 85%, which is very good. Keywords - Error: This tag contains too many keywords. This tag contains 16 keywords. This is too many for what we would consider a 'robot friendly' web page. The maximum number of keywords we recommend for this tag is 8. The keywords relevancy to page content is 75%, which is good. Widexl.com result Title - Title meta tag contains no errors. This tag contains 68 characters. Description - Description meta tag contains no errors. This tag contains 130 characters. Keywords - Keyword relevancy to page content is good. The keywords relevancy to page content is 75%. Vipsem.com result Title - Title relevancy to page content is good. The Title relevancy to page content is 92%. Description - Description relevancy to page content is good. The Description relevancy to page content is 86%. Keywords - Keyword relevancy to page content is terrible. The keywords relevancy to page content is 0%. Domaintool.com result Title Relevancy 80% Description Relevancy: 77% relevant SEO Score: 87% (what does this mean)? They gave different results but Vipsem give my keyword a terrible result. With such result, do you think my site has a good chance to get indexed by search engines (regardless of links)? Thanks
Those sites just give you results\answers based on their SEO beliefs. Don't get me wrong, they all might be the same book just a different page. Take them with a grain of salt and compare results to find an "average".
