Your budget is very low.

I’m actually surprised that your consultant pays that much attention to the account given the low budget.

Yes. they’re correct you should not consider Google Suggestions. Google’s Suggestions are there to syphon more money out of you.

200 keywords is a lot, specially on a $10/day budget.

As for how you select keywords, it’s the same as when you’re thinking about organic SEO. Think of your customer & your customer journey, and what searches and queries they might make when looking for a product / your offer.

For Example: I work w/ a dentist clinic that has a low budget. If I allocated their budget to general search terms or even directly services, they would blow through their daily budget in a few hours.

Instead, we opt to target people that need a dentist but aren’t currently looking. People searching for Tooth Ache Remedies, Gum Pain, Bad Breath etc etc.
