Hello all,
 
I was just wondering. I've designed my site using HTML5 and CSS3 and I've checked both google and bing web master tools and they both state my mark up has no faults, but I was wondering how to keep maintain my SEO in order for both google and bing keep ranking my site.
 
Are there any free SEO tools that I can use to maintain this ranking or does google and bing automatically maintain my rank? I'm new to SEO so if there aren't any free tools aout there how can I utilize google and bing to their best advantage?
 
Thanks in advance.

Thanks. I've just inserted the explode function into my other function that outputs the table. You're right it works fine. I put the explode function into my foreach loop and it only read the first element as all I was reading was the first element, (line), but when I inserted it into my other function and typed var[0], var[1] and var[2] it works fine thanks.
