In affiliate marketing, we see the word upsell when selecting products. What is this upsell ?

I am Nijara Borah aka Angel. I am a blogger and a marketer. I love to write or to be frank with you I love to write about my experiences. I think that's the reason why I love blogging. I am a blogger for more than a year now. I have been reviewing and sharing my thoughts about the products and services I use. I have a lot of good reviews and a few not so good ones too. Above all, blogging has given me an opportunity to meet a lot of people on this beautiful planet. I'm a very positive person. I sometimes get sarcastic but that's my nature. I also have a blog named make-money-quickly.com . It's about my blog and other things I love. View all posts by Nijara Borah
