There's a video from one of the WA members on combining google keyword search tool with google competition KW tool for domain name selection. 

Settings in Google keyword:

1st step: location set all  (instead of Canada or USA or any region you live) 

2nd step: on the column tab located on the right (check global monthly search) uncheck rest 

3rd step: do a blank search and find the match types (broad, exact, phase) on the left side of the column 

Starting phase: 

1) Find keywords using phase or exact match types. 

 2) Aim for at least 1,000 phase result or 700+ exact result

3) Go to google competition tool in WA and type these keywords 

4) if it's good use this for your domain 

Keywords used for Article writing: 

1) look for 100+ exact searches

2) write articles on street article using these target keyword 

3) expect 50-70 search/month for that article to drive free traffic. 

4) keep writing articles and repeat step 1-3 

Please feel free to expand or if there's any better techniques let's share it here:)
