Dear DP user ! I am getting following error when i try to check css validation from http://jigsaw.w3.org/css-validato as Sorry! We found the following errors (3) URI : http://www.sbglobal.info/default.aspx 225 Property -moz-background-clip doesn't exist : -moz-initial 225 Property -moz-background-origin doesn't exist : -moz-initial 225 Property -moz-background-inline-policy doesn't exist : -moz-initial My url is http://www.sbglobal.info But we did not find any such property in our css or webpage. So guide us what we have to do to remove such css vaidation error so that we can make our website seo friendly.
I'm looking for the error but cannot find it. However, I do have some good news for you. The errors won't harm your SEO efforts. (Seriously, it's a myth in 99/100 cases.) Edit: FOUND IT!!! It's in your home page's HTML code. Not the stylesheet. <a href="seopackage.aspx" title="SEO Packages" style="background: transparent url(images/rgt_menu.jpg) no-repeat scroll 0pt -27px; -moz-background-clip: -moz-initial; -moz-background-origin: -moz-initial; -moz-background-inline-policy: -moz-initial;"> SEO Packages</a> Code (markup):
Hi, There is a link in right sidebar -> packages : SEO Packages , which has an inline style that contains this mozilla specific style. Thats the reason you got the validation error.
Huh, there's one case out of a 100 where a vendor-specific property affects SEO? Or do you still mean affects a user == affects conversions etc? (since some people lump that in with seo)
Yeah. Keyword stuffing via cloaking. Take a DIV or list, throw a bunch of keywords you want to rank well for, and then add display: none; or position: absolute; left: -999em; to it. We won't see those keywords, but the search engines will.
So, did you mean something weird like -moz-display: none or something? My question was, is there any case where the vendor-specific extensions affected SEO?
