Both Microsoft Excel and Google Sheets are excellent spreadsheet packages and are extensively used on a daily basis by the SEO community at large.
The trouble is there’s only so much data wrangling you can do in either software package before you start to run into issues with data limits.
An excel spreadsheet can handle 1,048,576 rows and 16,384 columns at a time.  Google sheets has a cell limit of 10 million cells or 18,278 columns.  Big Query is a great alternative if you’ve started to reach these limits as it is designed to handle big data and is much more versatile – it’s also unlimited!
If you are an enterprise SEO team tracking hundreds of thousands (or even millions) of keywords daily then you need more firepower to store, manage, manipulate, analyse and visualise your SEO data.
Google Big Query is the perfect solution and it’s relatively cost-effective.
