My website (cockapoocrazy dot com) uses Blogger / Blogspot hosting. I just noticed in my Google Webmaster tools that my sitemap was only indexing 26 pages of around 150, which is apparently the norm for Blogspot blogs, to my surprise. That means it was ignoring over 100 of my posts for over a year now!
I submitted a proper XML sitemap, with all pages, to Google. It worked. Still, I know very little about sitemaps, and I had a few questions.
1) Is the sitemap very important and why?
2) Does the sitemap affect search engine results, ranking, or any other SEO factors?
3) Am I likely to notice any difference in traffic, search results, or any other area?
4) Will Google automatically use the sitemap I generated and submitted to crawl permanently, or will I need to upload a new one every post?
Sorry if these questions sound dumb, but my searches on this subject turned up many answers that were contradictory, unclear, etc.
