Here are some great links to help understand your data
Campaign URL Builder from Google. This will allow you to add UTM parameters to your URL. This assures better attribution in your Analytics tool of choice.
Google Trends. Check the keyword search volumes over time and geography to make sure that there is enough interest in them to build paid campaigns.
Learn Regular Expressions. When building segments and filters in Google Analytics or just plain coding in Python or R, you will need to use regexes. This is a good learning resource for them.
Testing Regular Expressions. When you have a huge list of URL’s and you need to find out if a particular Regex fits them all, this is a good resource to use as a check.
