Hi Guys, I am working on a site,I've ranking few KWs for that site. But I'm working on 2 new KWs and I added those KW in meta title & in H1,H2 tags. So far I've built 5 PBN links and 2 guest posts for those 2 KWs. I used partial match,long tail and exact match anchor. PBN and guest posts site are very quality sites,but so far zero results. It's been 15 days those KWs didn't even come in under 500. I'm very stressed,don't know what wrong going on. Other KWs ranked but they aren't. Putting all the efforts. Your help is appriciated. Thanks!
