Ok, i read your recomandation and i tried few things, but the truth is that i dont even know if there is a problem.
By the SEOquake Diagnosis, from the toolbar, i become the massage that the sitemap is missing.
I talk about a project of mine Mailcom.
Why does the Plugin do this. Even if i have two sitemaps generatet.
Doess the plugin dont send the sitemap on auto?
I just am afraid to do things wrong. I am new in SEO... sry.
Anyway thanks for all, and sorry if my english is not 100 percent.
