How to automate the creation of ads for contextual advertising?

Question

contextual advertising

Of course, manually creating all possible combinations of keywords for dozens of landing pages is stupid. Usually we have several sets of keywords under one ad. Somewhere we need to automatically add the words "price" and "buy" to the keywords and create a separate ad group.
Substitution of standard phrases in the ad title.
I have heard and use similar automation using excel, where you can implement phrase substitution and automate sets of keywords.
But it's still "write your bike". And there is no automation based on communication with the engine.
What services and programs do you use to automate the creation of contextual advertising ads?

Answer 1

You don't need automation software, use dynamic keyword substitution in your ad. This is available in both AdWords and Direct.
If you need to create automatically, use the API, or, for example, JS scripts built into AdWords.

Answer 2

I use ad generator for Yandex.Direct . 1500r. It's nothing compared to the time saved.

Answer 4

I use a new tool, at least for me - a free resource https://prodvizhenie.tv/direct to automatically generate Yandex direct ads. This is a by-product of the website promotion service, but it works great.
