1. Where is the sidebar?

In the global website template, the order of page elements was: head, sidebar, content, footer. Content and sidebar were divs floated to the left and right respectively, but in terms of a search engine spider, the sidebar’s contents (in this site’s case - the basket) preceded the main content, and therefore considered more important. One simple reversal has no effect on design to the end user but changes the complexion of a search engine’s interpretation completely.

2. Strip unnecessary javascript

Every little helps - if your site is referencing javascript that isn’t used, get rid of it. though the few lines of code you save have a negligible effect on SEO, you could be saving valuable seconds in load time. You can always put it back in if that lightbox or scriptaculous effect is absolutely necessary.

3. WYSIWYG code bloat

Cubecart’s page editor is quite guilty of embedding superfluous <span> tags for page styling. Particularly on front page and category pages in an e-commerce site, code bloat like this ought to be stripped.

The magic function is rand() which returns a random integer. There are two uses

int rand  (void)
int rand (int $min , int $max)

If you don’t supply any variables, rand() returns a random integer between 0 and RAND_MAX. RAND_MAX is usually 32768 on Windows systems, if you need a higher value, then you need to specify a $min and $max variable to generate a larger range.

If you supply a range of integers to rand(), then the range of possible values between $min and $max inclusive.

Examples

<?php echo rand(); ?>

Could return integers such as 7734, 1981, 2, 0, 30929 etc.

<?php echo rand(1,5) ?>

Will return one of the following: 1,2,3,4,5.

<?php echo rand(15000,50000) ?>

Will return any integer between (and including) 15000 and 50000.
