Will redirecting help?

I have domain 8 months old,and I was building links on it,lets say my niche is "subway surfers hack" and my other niche is "clash of clans hack" (just example). My subway surfers hack website was ranked as #3,but I didn't paid hosting and it went down. Then I paid,and now it's up for #40 for like 2 months,and niche is falling down so I don't want to try to rank it again. What do you think if I just redirect it to my clash of clans hack website(I am ranked #5 now for niche),should this help in anyway? Niches are both hack for android games but name is different etc. What do you think?

if they are related this could help you bump your site rankings for sure
just be careful the 301 redirects doesnt always work like onw would expect, sometimes it does and sometimes it doesnt, thats my experience with it tho'

Best of luck

You can try for it. But there is no guarantee whether redirecting will help for you in this situation because though both are same android games but it has different names...

As already mentioned, sometimes it works with 301 redirect and sometimes nothing! I have mixed results doing so on different domains, it's worth to try.

I just redirected 2 sites that I have,and that I used to try to rank before but didn't. So I hope that should help at least a little bit.
