Google AdWords is an advertising platform where we can see many features, from this we can organize performance information that can be generated by your account, campaign and ad groups. From Google AdWords we can choose how we want to reach our customers, with text-based search ads, display ads, YouTube video ads, in-app mobile ads, you have many ways to reach your target customer with AdWords. We can stay local or global to our potential audience within a mile range of your business, with AdWords you can broadcast your ads to entire regions or countries. Take the guesswork out of advertising, see if your ads perform perfectly or not. From here we can see what you need to do before the old AdWords UI is retired:

Rules and reports work correctly, to ensure your filters:

When your data and most of your reports are pulled into the new UI, there are a number of reports and rules that have been changed or rejected altogether. For rules and reports, any rules that rely on a column that is no longer available in AdWords will no longer work in your account. Remember that before the old AdWords user interface was retired, filters meant that using these columns meant nothing more.

Rules and reports that will continue to exist but with notable changes include:
The rules and the report contain columns that will no longer exist.
It also contains child accounts that are no longer managed by your MCC.
Reports that use columns not yet supported in the Report Editor, such as: Historical Quality Score, Landing Page Experience, CTR, and Ad Relevance.
We should also note that reports that are currently in .XLSX format will be converted to .CSV format.

Taking a tour gives you real tips, from where the important things live within the new user interface. it also points out the locations.

The navigation panel, which allows you to jump between active or inactive campaigns and ad groups of a certain type, such as (search, display, video, purchases) or all of the above. Google has created a kind of map to make it clear where things live and how to get there:

The page menu is the biggest new features, allowing you to change everything from extensions and tweaks to clients and change history.
The new home for tools and reports.
The help icon (very useful!).
And finally, the overview tab, which offers some very warm account-specific information for your viewing enjoyment.
