Link to your Twitter account from your website using the HTML anchor tag. Supply your Twitter account's home page as the URL and either some text or an image as the link. When visitors to your website click the link, they'll go to your Twitter account. The Twitter buttons page provides different sizes and themes for some buttons you may use, and even supplies the code for you if you click on them, but you may create and use your own Twitter buttons as well.
Open your Web file. Insert your cursor where you want to put the link to your Twitter account.
Type the following:
<a href="Follow">http://www.twitter.com/YourTwitterAccount">Follow me on Twitter</a>
Replace the "YourTwitterAccount" portion with your actual Twitter login name.
Save the file and upload it to your Web server.
