1. Choose your book.
Pick something that's been released for at least a couple of weeks but it doesn't matter whether it's frontlist or backlist. Arguably a backlist title should perform better in this test as it would have been available for a longer period of time, but there are parts that are essential for frontlist titles and pre-order campaigns.
2. Type the name of your book into a Google search. Don't hit enter.
Let Google's predictive search load up. This will tell you what people are searching for alongside your book title. In the example of ‘Fifty shades' (I hope nobody looks at my search history), what comes up is ‘Fifty shades of Grey', ‘Fifty Shades Darker', ‘Fifty Shades PDF' and ‘Fifty Shades Movie'. This tells us a lot already. Firstly that the book title is the most searched term. Secondly that people want to read the next book in the series.
