Welcome to the Q&A Forum

Considering the similarity in search intent, I think it would be a bad idea to produce multiple pages each targeting one of your keywords. I'd try and get them all on that one page, using different variants of the keywords on the single page and structure it into sections with headings that would be helpful for the user. If that one page is already ranking well for all three terms, it can easily just be improved. Rather than creating more pages and have them all competing against each other for the same keywords - and effectively sabotaging themselves.

Glad you've got the load time down, if you've get any benefits in terms of rankings/conversion from the change i'd love to hear about it. Best of luck with the site.

Hey There I know this question is a little old but just want to add some things. If we're talking about volume only - and getting accurate numbers from the Keyword Planner there are a few important things to know. First of all - the changes are just calculating the numbers in slightly different ways. They are still accurate, so long as you know what's different. For one, volume for desktop and mobile is now combined together - there is no separate report at the moment for desktop vs mobile so you're seeing these volumes combined Next is they are now averaging volumes across the last 12 months (which before I imagine they may have pulled from the most recent month) Now you can also not only get volume by country but also by city, state, region etc. Lastly - they are showing you all exact match volume by default - which is what you want. Broad and even phrase match are not very ideal for SEO. So when you go into keyword planner, it's actually easier in my opinion to get the right data. You don't need to set a match type. You don't need to add up desktop and mobile and they have average the last 12 months for you. The only thing you need to do really is decide on your location. If you want to know how many people type "french chocolate" in France vs. the whole world or vs. Italy - that's the biggest choice you have to make really.
