Determine actual state
First, determine the loading time for the really important pages. List them in a table and use Google PageSpeed Insights to determine the speed index for mobile as well as for computers. Perform several tests, because results can depend on the current load of the infrastructure.
First, it’s time to harvest the low-hanging fruit. To do this, remove all unused plugins, widgets, and features. For example, a barely used comment function or share buttons.
Check which tracking and analytics scripts that are no longer needed are still running and remove them. At the same time, you can set up tag management. Best on the server-side.
Internal redirects can also be removed. It is better to keep links always up to date.
Set up CDN
Quick to implement and effective is the use of a Content Delivery Network (CDN). Its use is particularly worthwhile for website operators who want to reach their customers anywhere in the world. Tip: The basic version of Cloudflare is completely free.
Identify particularly slow pages
Identify pages with particularly long loading times. Often these are those that include particularly memory-intensive visuals. Graphics should generally be no more than 30-40 kilobytes in size. However, the number of graphics is equally important.
You should never embed videos directly. Host them on Youtube or Vimeo and embed them on the pages.
Your website is still too slow? Then the webmaster should deal with these questions:
- Has caching and data compression been enabled on the CMS?
- Were compression methods like gzip or Brotli activated? (Tool for testing)
- Is the hosting in combination with the CMS too slow? Saving money on hosting rarely pays off!
- Does the CMS offer too few optimization options? Not all scripts, fonts, and content have to be loaded during a page load.
Making a website faster is usually possible without much effort. In some cases, the use of a new CMS or more powerful hosting is worthwhile. When used against conversion killers, this should be a good investment.
