Okay, here we go, something concrete.

First things first, go find what is taking up all your space. If you're not properly expiring old logs, they are a prime candidate for taking up too much space without being too beneficial. Check /var/log/ or whatever else directories your might have configured to store your log files. (Some shared hosting environments may pick ~/httpd_logs/ or something similar. Look around.)

If you want to keep your old logs for analysis, compress them:

gzip -9 *.[1-9]

Many systems rotate logs through access.log to access.log.0, then move .0 to access.log.1, then move .1 to access.log.2, etc. So the above command compresses them all with gzip(1)'s highest compression level (plain text log files tend to compress really well). Then you can transfer them off your small storage hosting environment for analysis. Don't forget to delete them once you're done -- once you take them out of rotation, they'll never get cleaned up automatically.

Then go hunting for space more generally:

du -m | sort -n

The last line of this will represent the directory with the largest amount of stored data underneath it. Lines earlier in the output are less full. This output will show you which ones will give you the best improvements for your time. (This won't necessarily be the ones that you should delete, but getting rid of one needless one-gigabyte file is way more effective than getting rid of one hundred one-megabyte files.)
