           Website speed is very crucial and major part of optimizin and monetizing your blog/website especially for search engines. The faster your site loads the more better for visitors and thus will create better impressions and make permanent visitor and will greatly help in reducing site’s bounce rate .
                  Its quite obvious that visitors will naturally ditch slow opening sites and switch to other ones , sometimes even though the matter they want is not available there finally becoming helpless only due to slow speed ,mainly due to bulky images , ugly ads and popups [yakk] .Website speed along with Page rank ,domain age , hosting etc  has a significant impact on search engine rankings as well . What i have observed is Wordpress loads faster than blogger and is most preferred Blogging Platform .
