Links, Links, Links
Apart from quoting and blockquoting text, linking is also important in the blogosphere. This helps your readers navigate to external sources of information. Links also act as recommendations. Links also help establish relationships among bloggers.
The best way to link is to link to a descriptive and useful anchor text, so a human reader knows the context of the linked website, and a search bot knows the keywords to rank the linked website with. So instead of using “click here” as the link to freewordpressthemes.com, why not say the best free wordpress themes around.
Most themes will highlight your links with underlines, bold text or with different colors. Sometimes, themes can also change the look of a link when you hover your mouse cursor over the text. You can also use the “title” attribute (that means <a href="link here" title="helpful text here"> so a tooltip would appear when your reader hovers his/her mouse over the link text.
