High traffic and low competetion = niches words that are easier to rank for.
Web hosting has lots of traffic,but you will NEVER rank for that word as there are thousands of high tech sites that are very good at
SEO that holds those positions.
But if you look at
best web hosting reviews VS
web hosting reviews
you will see the difference one word will make
Results 1 - 10 of about *7,990 for allintitle:best web hosting reviews
Results 1 - 10 of about 104,000 for allintitle: web hosting reviews
(allintitle: shows those sites that have the keywords listed in title and are trying to
seo for that keyword)
The trick is (of course) to finds those words that are being searched for that have low comp.
*7,990 is pretty tough comp for someone just starting out so I would look for a good hosting niche
