Blogger is a blog publishing tool developed at Pary Labs . Then it’s bought by Google.Inc. Initially it was as simple as a weppage then Google made many changes in both look and perfomance wise.
WordPress is developed by WordPress foundation. It is a content management system. It will allow the user to manage webpage / site easily . It is available for free as well as paid .27 % of the total web traffic comes from WordPress
What’s different between them?
As said early blogger cannot be installed in 3rd party web servers. Where as WordPress can do thia easily . Customization option in WordPress is far better than blogger . And also WordPress more search engine friendly I.e it allow you user to install SEO plug-in like yoast,meta tags,ect . There are huge number of template themes available for WordPress. If it’s a free version both are more or less same but if you move to paid version WordPress is undoubtedly the winner .The only thing that made blooger so good is it is easy to get adsense approval of you have an uniques content and certain views .
If you are looking to make money without spending a single penny they blogger is the only option but if your looking to make a website for other purpose like business, personal..ect WordPress stays ahead .
