6 Top Tips on Reducing Bandwidth

If you’ve read my earlier post introducing web hosting and bandwidth you’ll already have a good idea why it makes sense to reduce the bandwidth that your site uses.

The first is the most obvious, using more bandwidth than your web hosting plan allows will either result in your site going offline until the end of the month or a hefty surcharge for any extra bandwidth you use above your allocation. Think of it like a bank overdraft, your host will let you use more than you have got but at a price! This ultimately forces you to upgrade to a bigger, more expensive hosting plan.

The second reason is just as important as the first, visitor convenience – as hard as it is for some people to believe it, not everyone is on broadband, there are a great many users who still use dial up and a high percentage of them are impatient; long loading sites often result in connection time-out, or the visitor just gives up and closes the browser. As a result you lose traffic, clients, and if your site is ads supported – money!

So, what can we do to reduce the data transfer for everyone’s benefit? Here are my ‘Top 6’ suggestions that everyone can use to bring their bandwidth usage down.

  • Clean table-less code based on a CSS layout will certainly improve page loading, as bloated and messed up code take longer for browsers to process.
  • Optimise the images you are using. This is by far the easiest way to reduce page weight. If you have Photo Shop or Fireworks all the better but you can use a free on-line optimization tool as well to almost half images size without affecting the quality.
  • Avoid using big images, if you really need to display wallpapers, tutorial’s screen shots, etc, make clickable thumbnails, which will lead to the full sized image. You’ll be surprised, perhaps even dismayed, but most visitors do not view the larger resolution images, so why waste bandwidth?
  • If you are really tight on bandwidth, you may want avoid using Flash header elements in your templates. These files eat up tons of bandwidth so if you do not have some mind blowing design to show off, switch to an elegant and sleek style.
  • Movies, music and other media files placed on the site could be crucial for your bandwidth usage. Unless you have an ‘unlimited’ plan, consider using one of the many free file and image hosts then and hotlink to them from your website. This will prevent the entire site from going down in case your downloads suddenly got too popular. Just bear in mind any limitations of the free host you choose.
  • Disable hot linking (i.e. direct requests of the file through your host). Free servers normally disable it automatically, but if you are paying for your hosting, go to your control panel and disallow it. You might be amazed how dramatically your bandwidth usage will decrease.
  • I hope this sheds some light into the whole bandwidth mystery for those struggling to come to terms with the terminology used. Remember, it is not an exact science and the more people you speak to, the more hints and tips you’ll pick up. No matter what level you rate yourself, you can do a lot worse than signing up to some webmaster forums to read and learn from other people’s mistakes and successes.
