Hyperlinking your hyperlinks
Adding links within your hub is easy, simply write what ever keywords or text that you want linking and then you highlight all of it by clicking and dragging the mouse over the text, this will make the chain link on your text editor visible (above).
Then you click the chain link and a window will come up with 3 boxes in the first one you add the web address you want the link redirecting to, in the second box you should put open link in a new window as you want your visitors to remain on your page, and the third box is to put some alt text in, try to make this keyword specific or related to your web url that the visitor will be directed to.
Click ok and save your hub!
Then you are done!!
Make more hubs forever and ever.......
Oh... one more tip! if you try and add relevant links to information to other sources preferrably your own content on your blog or website, you can build up some credibility within the search engines and create your own mini networks that will rank higher than some other pages on the search results pages for your chosen keywords, remember to use anchor text for these links with your best keywords!
An example could be backlinking strategy and so you could bold this keyword phrase and link it to a relevant site with those same keywords at the forefront, you may find a few blog posts that match the keywords well, so link to them, but I would consider writing your own stuff here on hubpages and linking directly to that, because you'd want to regain the traffic on your own pages and not some other site really.
Anywhere were you can place a good keyword hyperlink back to any of your hubpages then it is advisable to do this to build up your own tight linked hubpage network with relevant content.
