Is it worth humanizing the title in Yandex.Direct ads? And what about the city?

Question

contextual advertising

Hello, tell me about my situation.
My key: Fitness trainer
I advertise only in my region (Rostov-on-Don)
What would be the best of these headlines for RK in Direct.
1) Fitness trainer
2) Need a fitness trainer?
3) Fitness trainer in Rostov-on-Don
4) Fitness trainer in Rostov
5) Fitness trainer in Rostov-on-Don
Questions:
1. Should I indicate the city if there is no city in the keyword.
2. If the keyword contains the city "Rostov", can I write "in Rostov" or "Rostov-on-Don", Yandex will pick up the occurrence of the word "Rostov", if the phrase "Rostov"?
For example: Fitness trainer in Rostov - and ad: fitness trainer in Rostov
3. If the keys are "Diet", "Workout", "Fitness Coach", then can I just make announcements based on the principle "Need a Diet?" , "Need a fitness trainer?" etc. and is it worth adding your city in this case if there is no city in the key?

Answer 1

Relevant heading is best :)
How do you feel about using templates ?
For templating, you will have to manually give all the keys the proper form, including the correct cases, numbers, prepositions, conjunctions. Well, grouping is important. However, due to "few impressions", segmentation is important anyway. Yes, and for the relevance of ads too ... or are you going only for HF-MF according to the 1-1-1 scheme?
In any case, the city can / should be indicated in the clarifications, the text of the ad, or, as they said in the second heading.
2. Direct does not take into account prepositions and cases (unless you explicitly order it to take it into account). So yes, you can safely use cases. And yes, Rostov-on-Don includes Rostov in any case, so it will be shown.
A nuance for the future: Rostov is also the plural of the word Growth. Therefore, there may, although unlikely, unpleasant surprises left requests. But I have no idea who asks Fitness Growth Trainer :)))
3. Why not? At least for the test, as the second announcement.
As for the city, what are you worried about? That ads will appear in the wrong region or that they will be less relevant? If the first - then in vain, the display region is configured in the directive. If you are worried: make one ad with the city, and the second without it, and see what will be converted and how.
Another option is to collect keys with the entry of the city into a separate group / campaign and play with it. And for other groups, explicitly indicate the city, for example, in the Heading 2 field. Just don't forget about the cross-backing track!
