Powering Up My Guest Posts

Hi guys, i recently started doing outreach and landed 5 links from very high quality sites. However, i am not seeing any movement after 3 weeks. I read somewhere that the guest posts need to be powered up by tier 2' to see effect.

How should i do that?

1. Buy auction domains and turn them into pbns, then link them to the guest post?
2. Blog Comments?
3. Web 2.0's?
4. Other spam?

Thanks

1 firstrly then 4 then 3 then 2

Still looking for some help, any replies are highly appreciated

Don't build links to a guest post, it is rude.
Either the domains you got posts are; not crawled/indexed, no-followed, yoursite sucks, or you just need to keep waiting.

I run a network of free guest posting sites(do NOT email me, no links available here) if I catch someone building links to a post, I remove their link, delete the post, redirect that post, and/or other things.
Build links to your own site.

It might take some time to reflect...check whether the article is indexed first...if not make the necessary edits..
