I would say mayank...I've seen your both websites tvserialupdates and windows update...
I liked them.
Usually I will tell you to write an guest post.
Write an guest post on TV serial and submit it to an blog. This will also get some traffic from their website.
Nextly for windows I would recommend create some awesome inforgraphics ...That is pictorial representation. You can create them on Canva.com and send to few of the bloggers in your niches.
Ask them if they want to use them ...If yes them ask them to give backlink.
