Dear Experts! Greetings from my side. I have a PR2 blog named yesiknowthat dot com. I recently used some online tools to check whether it is properly SEOd or not, but according to that tool it is not properly SEOd and it showed me a lot of errors. Also it said that my Sitemap and robots.txt is missing but I think they are added to my website. I performed this test through woorank.com, now I just want to know whether this tool is reliable or not also I need experts reviews on SEO of my blog. And I would be thankful if you guys also tell me about a reliable tool to check the blog's SEO. Thanks
Your sitemap and robots.txt are present and working fine. I would take what such free on-line services say with a pinch of salt - it's clearly mistaken about the sitemap and robots.txt.
I have visit your site. I think you should improve some SEO factor, such as hot to optimize your CSS script code so that you can optimize the blog performance. About your robot.txt, I think its OK.
