COPYWRITE AND CONTENT

Apparently every site owner needs to make absolutely sure that your
content is unique and that you did not take any text from another site.
This used to be fine, just change the text and now you own it. But Google
has cracked down on this big time. Sites with a PR of 5 and up dropping to
0 immediately because of a copy write issue. Just as a precaution check
out www.copyscape.com and punch in your URL, find out exactly how many
people have similar content. Be specific to pages as well, it only
checks the page you tell it to. Great tool

Having clean HTML is a very important step. If the crawler gets lost,
it has nowhere to go but somewhere else. Validate Markup Here
