I need to redesign my outdated website...

Websites are usually upgraded every 2-3 years to meet the new business needs. However, to create a functional and effective website upgrade, you could consider the following suggestions:

First, you should do a thorough website analysis for the current website, and learn what was working, and what was not. By reviewing the current website statistics, you can inherit effective features of the current site, while upgrading the ineffective sections.

Second, you should look at the websites of some of your big competitors and see the web features they provide in their websites. You may have some good ideas about the functionality of your new website.

Third, you should review the goals of the new website and your budget. There may be many "nice" features to have, but with the given budget, you may want to pick just the key features that best support your visitors, and save the other nice features for later upgrades.

So now you can give your website agency the clear website goals, the customer insights gained from the old website, the key areas to improve, and some good competitor websites to look at. Your website agency will find it a lot easier to deliver you the best website you expect. This will also save a lot of time and energy for on-going communication and troubleshooting between you and your agency.
