An Interesting Thought to Ponder

Should one create 1 big authority site covering an entire niche or a big part of it, or create 10s micro-niche sites (having the same content topic of 1 post on that authority site, but expanded of course.)

On one hand, 1 big site will have a better chance at actually becoming an authority for its niche and thus will have an easier time ranking and getting traffic from different sources of keywords. Moreover, major costs will be reduced such as hosting, web design, domain registration fee, etc...

On the other hand, a Google update could hit and destroy months of work on that authority site, while if it actually did hit a micro site, you won't feel it since you will have many other ones.

I'd like to hear your thoughts on this

Diversify friend diversify exactly your thinking is correct...

I think it depends on the niche, if you are able to corner the market in the niche and become the #1 in all aspects,then one big site may be best if your seo is done with quality.

i have made this mistake , authroity sites some time take alot of work thats y now i stick with micro niche emds and rank all ten keyword easily

I would go for mini authorities, then expand and build those authorities, this way you won't get burned like everybody else...

Working an authority site is cool but always have a backup site, cause even whitehat authority sites get slapped, alternatively do both, have an authority site then a bunch of smaller sites...

Neither is a better strategy over the other.

It depends on what route you want to take, what you're good at, and what your goals are.

Both models can yield good results.
