RE: How to start twitter marketing for e commerce sites?
One of the effective ways of promoting via Twitter is by using Hashtag Strategies.
Make sure to use keywords that describes your product or label, and your target market. Just keep your keywords simple and direct.
#yourbrand #yourcompanylabel #targetmarket
Also, don’t forget to take advantage of Follow Friday. It is a weekly event on Twitter, wherein Twitter users would recommend their followers to follow more people.
