I keep getting an error when installing sitemap onto my numerous sites. Saying error, code has not been installed. When i have installed it. How do i fix this? Im also wondering how or if i install sitemaps for blogspot blogs?
What do you mean by installing sitemap? A sitemap is something you usually upload? What is giving you the error? Google Webmaster Tools or...?
They only current way to create a XML Sitemap for blogspot is if you use the custom domain feature or host the blog on your own web server\web hosting account. This is because you must upload the xml file to your top directory.
I have uploaded a "meta tag" into the title/heading of the page. As it says to add it in the first "head" section of the page. Yet it does not verify. Its a problem with google webmaster tools i think. ?
That depends on where to place the tag in the index page. I encountered similar experience and google itself will tell you where to paste the code. Being a verified customer, you are entitled to learn a lot about your website stats like diagnostics, (to locate the problem), links, index stats etc etc. You can collect information only for your site and not for others and that is the reason why google want to verify whether you are the real owner
