Step 1: Open Google Keyword Tool
Step 2: Launch SB and open the keyword scraper.
Step 3: Enter any keyword. For example, enter "apple" and start scraping.
Step 4: After scraping is done, remove duplicate keywords
Step 5: Enter those scraped keywords again in the keyword scraper and start scraping.
Step 6: Repeat step-4 and 5 using keyword scraper until you find all the long tail keywords.
Step 7: Now you have a huge list of long tail keywords. Copy the first 100 keywords and paste it into the Google keyword tool. Enable the option "Only show ideas closely related to my search terms" and search.
Step 8: We want the exact search for the entered keywords so under match types select "[Exact]" and search again.
Step 9: Sort the result from high to low search count. Now you have the exact keywords sorted by search volume.
Step 10: Ignore all the one word and two word keywords. Start analyzing the first page competition and the EXACT keywords domain availability. I'm not going deep into the competition area, I leave it to you.
Step 11: Now copy the next 100 keywords and repeat the step-7, 8 and 9 until you finish all the keywords in your list
Step 12: Once you find a high search volume and low competition keyword, build your website and monetize it.
