Google will find your blog. So, if someone carried out a search of your name in Google, it is highly likely that a link to your blog will be listed in the search results. However, it is up to you to decide if Google finds individual entries that you write. If you set the privacy level to be completely public then Google will find it. However, if you restrict the privacy level at all, then Google will not find it. An easy way to tell is to look for the padlock icon next to the title of your entry once you have published it.
