Hello all!
I created a site on blogspot.com which is a very useful one. Unfortunately, when i search the related keywords on the search engine (which are almost unique to my site's contents and only 1-2 other similar websites are created), I'm not directed to my website.
I read somewhere that adding metatags and sitemaps will help the ranking of your site and the site will be showed on the search list.
Then,
I added my site on "webmaster tools" and also created a sitemap using some application. Unfortunately :(, I'm not able to upload the sitemap in .xml format to my site (.........blogspot.com). What shouldd I do?

Also, When I tried to add the metatags in the posts with relevant keywords, an error in red font was displayed. :( :(

please help me, what should i do?
