Twitter allows users to embed a widget on their website that shows a users recent tweets or the tweets of a particular hashtag. Notice on the left hand side of this blog is a list of the recent tweets from @alicekeeler. On my classroom website I have a widget on the side to display tweets that utilize the class hashtag.
If you want your widget to display a particular hashtag click on the “Search” tab along the top. In the Query field change the default search hashtag. Be sure to include the #. Click on the “Create widget” button.
You will need to paste the code into the HTML view or source view on your website. I paste my code into the widget space on this WordPress. Paste (Control V) the code. Note that these widgets will not embed into a Google Site.
