@rahimhussainali ... you asked:
In the end i will copy jobs from other website.
I will be blunt: Your site will drop like a rock and not be found.
COPY SITES do not fare well. Even if you COPY and generate a bit of NEW to go with it you still will not rank well.
Aggregators have lost love over the last three years and that will only get worse.
(Aggregators are sites that use OTHER FOLK'S CONTENT as their own while attempting to LOOK like they are fair and not using other folks content.)
Original aggregators ala 1998 to 2000 who actually built a following get a pass, but nobody since then can actually do well.
Develop real content, something unique, and take your best shot. Even then there are NO GUARANTEES you will do well, but at least you would have a fair chance!
Hope all that makes sense. Some things you can legitimately copy (with attribution), but basing your entire site on "copy other websites" simply will not work in today's web.
The search engines, nearly all of them, are on to that trick and they DO NOT LIKE IT.
This is a very good time to re-think site direction and intended goals.
Good luck!
