The root version was done by another webressource. Now I am using Zencart since a good year I just realize the Google ranking problem.I do not have very much experience.

In root I have:
page1.html
page2.html
estore folder
order.php

I just found that I can put in each program a php redirect line. I taught that htaccess was they only way.

Also I wonder if it not better for ranking purpose to put Zencart in root folder?

Thanks a lot Dr. Byte for looking my problem.
