I have a lot of backlinks to my website. And they are being added daily. But with all this, my website is going down on SERPs... I'm targeting "anunturi" and my website is serviciionline.net Can you take a look at the source code to see if everything is alright? Because I think I'm getting penalized...or...I don't know. Is my keyword density too high? Do I have too many title attributes containing the keyword "anunturi"? It's a daily battle with Google and I never win. Thanks!
Getting Backlinks from relevent site is more important than just getting backlinks from anywhere. so you should try to get backlinks from relevent sites and use your important keywords in link building so that serp will increase for that keyword.
I think u need to check ur proper site may be there is anything which google dose not link. and you should update your complete content it can help you to get back on SERPS
