Let’s take the following piece of HTML that might be in your webpage:
<a href="previouspage.htm">Click Here to go back 1 page</a>
This example above would place a link on your webpage asking the visitor to click on the link to go back to the page which they have just come from.
Now the only problem with this is if you don’t know what page they have actually come from then you are totally stuck and you don’t really know where to link them too. This can be resolved using the following replacement for the above example:
So by including the above html exactly as show, it will give your visitors the option of viewing the previous page.
