Hi, can you please explain the question a bit more clearly? However, let me try to address it:
To view the search volumes for keywords/phrases in Google from so and so geo location, you can use Google Keyword Planner, here:
https://adwords.google.com/KeywordPlanner
You need to login to your Google account to be able to use the keyword planner.
Once you have your master list of keywords/phrases based on relevance and search volume, you then need to think about keyword mapping which is a process that involves, coming up with keyword/phrase specific pages to be added to your website targeting each one of these keywords/phrases. So you will be mapping these keywords/phrases to your URLs (pages). Here is an example:
Suppose your list of keywords has a key phrase, "mutual funds". You can map it to a page URL like:
yourdomain.com/mutual-funds.html
Likewise, you beef up the size of your website with pages targeting keywords that resulted from your keyword research and analysis using tools like Google Keyword Planner etc.
Once you are done with keyword mapping process, you get down to write the content for each of these pages. You also need to optimize the on-page SEO elements on these pages like, the page Title, Description, H1 tag, content itself, contextual linking (internally to other pages) from within the content etc.
Please feel free to elaborate your query so that we can address it more accurately.
By the way, SERPs means, search engine results pages, the ones that Google or any other search engines give us when we search.
