I looked on Amazon's site and it didn't tell me much. At least not that I understood.
This is probably an impossible question to answer but I'm going to try anyway.
A website with 30,000 views per month. 7000MB of disk space used and total bandwidth of 60,000 MB per month. I don't even know if these factors are important.
I looked at their fee estimator and was lost.
I need to improve speed. Last month Google showed me as 98% slower than other sites. So I made some tweaks. I installed super cache and minify. Their latest measurement shows me at 100% slower than other sites. LOL Not a good trend. I was getting a lot of 500 errors so I upgraded to a VPN which I hope will help and may be the reason for my horrible stats per Google Webmaster tools.
I'll go ahead and put the site in case that will help answer the question. cebuexperience.com
