Basically, Google shows the autocomplete suggestions whenever you start typing anything into Google search box.

For businesses where the value of a potential transaction is high, such as a B2B service company, it may be useful to target very specific phrases with very few searches.

To find keywords which generate traffic and conversions, try to use modifiers that are appropriate for your niche.

People looking for quality use modifiers such as ‘best’ or ‘elegant,’ while those looking for the best price use ‘cheap’ or ‘discount’ to find your product.
3. Ninja Outreach: Full disclosure this is my own tool, and it is actually an outreach tool, so you may be wondering how it plays into Keyword Research. The fact is there are quite a few data points that NinjaOutreach gets for me that I find useful in keyword research, such as the articles that are ranking for the keyword in Google, their domain authority, their page authority, the number of backlinks they have, and other social and contact data. It's pretty valuable stuff, especially if there is going to be an outreach campaign tied into the keyword research. I wrote a great article with Jake from LTP showing the combination of the two tools.
To qualify to appear in the snack pack or the resulting local search pages, your business needs to be verified by the Google My Business service, which involves registering, getting a physical post card from Google with a code, validating the code and setting up perfect NAP (Name, Address, Phone Number) data across your site, Google Maps, and other citation services and directory listings.

I like how you say thinking like the end user, as I feel that way when I search. I dive into what people are looking for and it really helps drive content idea’s. I have seen great results from that.
