where they get the money to host so many blogs, and so many pics. yet the service they provide is free
Yes, advertisements. Some of you might say, "Why don't I see any adds being put on my blog?"
Now this is the magic of Blogspot marketing. Theres Adsense on blogspot. After an indivisual or group paid Blogspot for advertising their products, Blogspot will allow bloggers to host these advertisements on their blog and make money using Adsense as well.
Because you can choose not to have advertisements on your blog, thus many people uses Blogspot and not other hosts. This will generate a lot of clicks for Blogspot, thus it can charge a lot more from cooperations who want to post adverts there. After getting this large sum of money, Blogspot will distribute this amount out to bloggers who are willing to host the adverts.
A good example will be the Xiaxue in S,pore. Look up her blog, theres adverts from Adsense
I also have adverts in my own blog. Though traffic is low, I just put for fun.
