It's spring cleaning time! Today is a good day to:
- Make sure your important domains are all registered at least a year in advance.
- Validate your CSS.
- Reduce redundant white space in your source code.
- Check the broken link reports in Google Webmaster Tools then do some fixing.
- Check GWT's query reports to identify searches where you have pages ranking in the top twenty but not the top five. Test some tweaks.
