Any way to determine what file is rewriting index.php to root?

In your zencart ADMIN CONSOLE, look under the TOOLS MENU and go to DEFINE PAGES EDITOR

Open the define_main_page.php for editing and add content to your heart's content...

There are numerous sidebox modules available that can carry additional content. The late (and great) Clyde Jones's TESTIMONIALS MANAGER is a good one... Google like this one.

You can build your own sideboxes using BLANK SIDEBOX and CLONES of it, to contain reams of content if you wish...

There are scores of ways of adding good, relevant and topical content to your site, and the home page is no exception....

Proper SEO is not just about landing page keyword optimisation. Google now looks at it very differently, and considers a wider range of contextual issues regading how it evaluates and ranks a site.

Go to THIS SITE, and spend a minute looking at the main (landing page).

Then go to google.co.uk and put this into the search field:

refurbished heating spares

(That is a critical phrase GENERIC for the website you just visited)

What appears on Google's search results in positions:-

• 1
• 2
• 3

What's quite interesting is that on Ignites home page, there is no content phrase that contains exactly refurbished heating spares.

Yet that phrase returns FIVE results* on page one of google.

*Positions 7 and 9 are relative to ignite, but link elsewhere.

If you are not located in the UK, Google may return different results. But as my client is UK based, those rankings are relevant for this region.
