My daily traffic is approximately 1500 hits per day with about 85-90% of that traffic coming from Google and other search engines.
That's just on this account. I have four other accounts I also write on which get about 200 hits a day but have a much higher CTR and Amazon sale rate - those are my money making hubs.
I don't backlink. I tried it early on, and probably have about 20-30 low quality backlinks floating around online, but I quickly learnt that I don't want to backlink here, coz I'd rather be writing.
Basically backlinking just speeds up the maturity rate of a hub. So I'd rather write 50 hubs that mature in 9 months than write 5 hubs that I backlink a lot and mature in two months.
Hubpages is a strong enough platform that you don't need to backlink if you learn how to use Keywords and on page SEO properly.
My other four accounts have few or no followers, aren't known on hubpages and have never been backlinked in any way. I write a hub, then I leave it. I don't do anything else to it (except an occasional correction if I had a spelling error or incorrect or updated info.)
Hope that helps!
