And this information is important, since correctly collected statistics allows for the effective distribution of advertising budgets.
Modern services are trying to solve the problem of multi-channel whatsapp number data statistics, but so far this solution looks primitive. There is no precise accounting of buyer behavior from different devices and identification of different users of one device. There is no clear algorithm for understanding the role of each advertising channel in the final purchase. All this is interpreted "roughly" and "by eye".

Of course, statistics services will gradually learn to collect and process complete data on user behavior on the Internet. But for now, this function lies with a person, and sometimes with a whole group of people.
4. Quality ads
Well-written ads will always be a part of effective advertising and are therefore very important.
There are now plenty of technical parameters when writing ads:
multiple headings;
extended descriptions of quick links;
the ability to call without clicking on an ad;
individual mobile ads.
How can these elements be combined to achieve maximum results?
There is only one answer: there are no rules. There are only recommendations, which, by the way, do not always work. You need to test, test and test. And absolutely everything: titles, descriptions, combinations of titles and descriptions, options for quick links and clarifications, and so on.
So, you need to set aside time and budget for testing - without this, it will be difficult to make good advertising in 2019. There is another good reason to conduct testing - our audience, which perceives different types of ads in its own way.
5. Video advertising
This type of advertising is not perceived by many as a means of increasing their profits and brand loyalty. Only a small portion of advertisers use it. The level of video content consumption is constantly growing. Users spend hours of their free time every day watching videos on YouTube. Next year, Google will continue to develop advertising capabilities and tools for video campaigns. Yandex. Direct will also expand the reach and capabilities of video advertising. Currently, video ads are part of text and graphic campaigns on the network; in the future, a separate type of video campaign may appear.
