Whois tool shows SEO Score 96% for my 1st website, and only SEO Score: 82% for my 2nd one. However, i cannot find mistakes on my 1st website. Also, my 2nd website doesn't has meta discription tag, but again i no see more mistakes there. How to check what wrong with my websites? Thanks.
see ypu do not need to use all these tools. just make sure that your website is W3c validated .. Otherwise you do not need to check other tools because you do not know in detail which factor they consider to give you ranking
