Digital Marketing Strategies Top Ad Agencies Use For Clients

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.

Retargeting is advertising shown to people because of something they did before: visited a site, viewed a product, abandoned a basket or appeared on a customer list, with the ad platform recognising them later on other sites, in search results or in a video feed and serving an ad tied to that earlier action.

Data visualisation is the practice of encoding numbers as position, length and colour so that a comparison a reader would otherwise have to calculate becomes something they can simply see.

Data engineering is the discipline of moving records from the systems that produce them into a store where they can be queried, and of keeping that supply correct while the sources underneath keep changing.

SQL is the declarative language for asking questions of relational databases: you state which rows and columns you want and how tables relate, and the database engine works out how to retrieve them.
