Nice post & I agree with the downtime server issue ... been there myself

I read the article but what is the meaning of htaccess???

 

.htaccess is a file containing various server congfiguration options, letting you change the way the server behaves on a directory-by-directory basis eg custom 404 pages etc.

 

If you change your .htaccess and end up putting incorrect rewriting rules, not only SE spiders, your visitors won't be able to see those pages. Robots.txt errors are harder to detect because you won't see them using your browser.
