If I can write up to 1000 posts for my website, can I get at least 1000 visitor/day for my website, without doing off page SEO like bakclinking, blog commenting
Are you relating the amount of posts to the amount of visitors you want? Wrong way to go if so.
Are you actually writing the 1000 posts yourself or spinning them? I'd assume because this is on the black hat forum, that you're planning to spin.
If you're doing it yourself - your straight up crazy. There's no need for 1000 posts.
You'd be much better off (IMO) doing 50 quality posts on your site over the course of one year; sharing them with relevant authority domains/people/etc will bare so much more fruit than 1000 crappy ones. I'm pretty sure I've seen a story like this before:
-The guy did 38 articles over the course of 6 months/12 months
-He done his outreach and targeted high trust/authority sites
-He experienced a steady climb of site views until he reached his goal (several thousand daily views)
If you want motivation: get a realistic or SMART goal. Don't get into the mindset of 1000 posts = 1000 views
I know I can write 1000 posts in these 8 months but dont know if that would help me getting 1,000 visitors a day.
No, it won't. Your time would be much better spent researching strong places to post and making 30-50 really, really good articles - no broken English, regurgitated, boring, nicey-nicey, generic or whatever stuff the black hat masses consider to be good these days.
Going against the grain can work really well sometimes - controversial topics always attract a lot of attention (obviously this depends on your niche).
Step back and think first...8 months to do 1000 articles...really?
