Want to speed up your website? It's well worth the effort.
The faster your pages load, the happier your visitors will be, and the longer they'll stick around.
Removing unnecessary or oversized content can help reduce your bandwidth requirements and save you money, too.
Of course you'll need advice on which parts of the site need optimisation, but that's surprisingly easy - we've uncovered free tools from Google, Yahoo, MySpace, AOL and more that will analyse any web page and point out how it can be improved. So which one is best? Keep reading for everything you need to know.
Yahoo!'s YSlow is an excellent Firefox add-on that will analyse a web page and deliver a list of helpful suggestions on how to improve its performance. It's integrated with the Firebug development tool, though, so you must install that first before adding YSlow itself.
Once set up clicking Tools > Firebug > Open Firebug will display load times for every part of the current page, so if one image or external link is particularly slow then it'll be immediately obvious.
We did notice one problem with YSlow, and it's big one: the current version doesn't work with Firefox 3.5. But once an upgrade appears YSlow will once again take its place as one of the best free web page optimisation tools around.
HELPFUL: YSlow clearly identifies the bottlenecks slowing down your PC
2. Web Page Analyzer
WebSiteOptimization's Page Analyzer is an online service that will check whatever URL you enter, then suggest ways to improve page performance.
This all starts with a simple list of page object types and the time they took to load (including estimates for several connection speeds), which immediately highlights any problem areas.
The Web Page Analyzer has some good advice to offer, then, and is a simple way to get started with web page optimisation. But if you're serious about revamping your web site then you'll want to quickly move on to a more professional tool.
SIMPLE: Web Page Analyzer is easy to use, but a little short on detailed speed-up advice
3. Google Page Speed
At first glance Google's new Page Speed looks like a YSlow clone: a a Firefox/Firebug add-on that benchmarks your web page and uses a set of best practice rules to let you know how you can speed things up. Play around with the tool for a while, though, and you soon begin to spot the differences.
