Book Marketing in Five - How to get your book noticed fast

Keyword research is the work of finding out which queries people type when they want what a business offers, how many of them there are, what each query means and what competing for it costs, before any page is written or any ad is bought.

Conversion rate optimisation is the practice of raising the share of visitors who complete the action a page exists for, a purchase, a sign-up, an enquiry, by changing the page and the path to it on evidence rather than opinion.

A/B testing is a controlled experiment on a live audience: visitors are assigned at random to two or more versions of a page, an email or a feature, and the versions are compared on one pre-chosen outcome so that the difference can be attributed to the change rather than to who happened to see it.

Data governance is the set of decisions and responsibilities an organisation puts in place over its data: who owns each dataset, what each field means, who may read or change it, how long it is kept and how its quality is measured, recorded so that the answers do not depend on who is asked.

Data quality is the degree to which a dataset is fit for the purpose it is used for, assessed along named dimensions, whether the records are complete, unique, consistent, timely, valid and accurate, and measured against the requirements of the decision the data supports rather than against an absolute standard.

Data modelling is the design of how data is structured for a given use: which entities are recorded, which attributes describe them, how the tables relate through keys, and, for analytical use, which table holds the measurements and which hold the context, decided before the data is loaded so that the questions the model must answer run correctly and fast.
