If you build some scraper sites only with one specific search term your website gets banned in the majer search engines fewer or later. It happends to me every week and I recognized that my keyword structure could be the problem.
The key to success is a latent semantic keyword reasearch! Don’t focus on one single topic.
For example lets say you made a website about bicycles. Use related search terms like bike, cycle, mountainbike, bike ….not only bicycle.
This cool keyword tool also catches information about competing websites, ppc clicks and costs per day.
It automatically filters out useless keywords like “bicycle.com” which is searched a lot and removes duplicates.
You get additional tips about the each keyword and its related market and you see if its worth to build a blog, write articles or doing press releases for this particular keyword. wow !
Give Themezoom a chance in your keyword research you will love it.
If you have enough time do it manually, I haven’t this time
