Are data analysts doing any data analysis?

Data analysts: How do they spend their day?

Data analysts and data scientists are the most popular jobs for the past couple of years, but how do they spend their time? How much of their time is actually spent on crunching numbers and looking for useful business insights? Most of the times data is really dirty and the burden of sanitizing a data-set usually falls on the one who is going to analyse it, the data analyst.

Exclude personal data from your web analytics

Personally Identifiable Information (PII) data or personal data (e.g. email addresses, social security numbers etc.) is a complete nightmare for web analysts. Every web analytics platform is very clear on this matter, that their systems are not designed to store PII data.

If you end up having your account deleted, the chances of bringing it back online are very slim. Adobe Analytics will also advice its users against storing personal data on their servers. Most marketers don’t need...

HTTP status codes

If you are working with analytics you have to know what each HTTP status code means. Every piece of information travelling through the webs is also carrying a status code with it every time it travels. HTTP status codes are standard response codes given by web site servers on the Internet. The codes help identify the cause of the problem when a web page or other resource does not load properly. Every status code consists of 3 digits and belongs to one of 5 main groups. The first digit of the status code indicates the general type of response (the main group of the status...
