# Introduction of Time Series Analysis For Digital Analytics

I have an awesome textbook on statistics. It covers most statistical things, but one of the things you will not find in this awesome textbook is anything on time series. Time series are different and that makes them really interesting to me. This is because the x-axis is time, with the y-axis the thing (KPI) you are measuring. Because of that, you need to use different models to predict outcomes.

In these models, the y-axis values are compared to other values on the y-axis (the lag values). For example, this month’s revenue is compared to last month’s revenue and the revenue of the month before, going all the way back to the beginning of the dataset. The chosen comparisons are based on the statistically significant lags. Last month’s revenue might be statistically significant to the current month’s revenue, but revenue two months ago may not be (but revenue from three months ago might be).

In this post, I will give an overview of one type of time series models and describe how they work in simple language. In future posts, I will describe how to implement the models in BigQueryML and in R.

# Getting Started With Screaming Frog SEO Spider

Yoast SEO can help with optimizing website pages.  Screaming Frog SEO Spider can crawl your website and report where you may have issues with your technical SEO – such as missing meta-descriptions or canonical tags.  You can also use it to check if your analytics tags are present on all pages. Let’s get started!

# Using Yoast SEO

This post is a bit of a deviation from focusing on data and analysis. However, I thought I would cover something that is very important if you have a website and want to drive traffic to it (and I do work in Marketing Analytics, so…). Search Engine Optimization (SEO) is the process of optimizing the content on your site so that you have the best chance of being picked up by search engines (mainly Google).

If you are wondering how to begin with SEO, Yoast SEO could be the answer.  Yoast SEO is known for its WordPress plugin.  However, their plugin is available for other platforms, like Magento.  But, I will focus on the WordPress plugin in this post.  Once activated, there will be a Yoast SEO section for each page, post, category & tag.

SQL is the language used to communicate to relational database management systems (RDBMS). E.F. Codd wrote a paper in 1970 describing a completely different way of structuring data. Up till then, data was generally organized in a hierarchical structure of some kind and a lot of code was needed to work with the stored data. Codd’s paper described a structure of storing data as relationships to reality as objects that have ties to other objects in the data structure.
