Today, while reviewing Marshall Lebovits' Show Me the Money blog, I became very conscious of the fact that Marshall makes good use of links within his posts. Most of Marshall's posts are commentary on other websites' articles on the subject his business specializes in. Marshall references these articles with a link to them so the reader can easily check out the reference for his comments.
When talking about something you found on another website or blog, go ahead and give it a link, and link specifically to the post you read if that is possible. This is what the famous "permalink" at the bottom of blog posts is for. Simply right-click on a permalink and choose 'Copy Shortcut' (Internet Explorer) or 'Copy Link Location' (Firefox) to load that post's URL onto your clipboard (Step 1 below). Then paste this into your blogging program where you would normally type out the web address for a link (Step 2 below).
You don't need to create a link every time you reference the same website. Once is enough.
Adding links in your posts will not hurt your search engine rank like a blogroll will. The reason is because this link will only be on your home page temporarily while a blogroll link is a permanent link on your home page. The more outbound links on your home page, the more your home page looks like a 'link farm' which is downgraded by search engines. It's okay to have a bunch of links on your home page, just make sure they are internal links that bring readers (and search engines) to pages within your own site.
Note: I added another post right after this one called Blog Don'ts #4: Don't use too many links in your post. Some links good. Too many links bad.
Step 1 -- Right click on the permalink and choose 'Copy Link Location' (Firefox):
Step 2 -- Paste link into your blogging program (in this case it is Typepad):
