Seems like, the kind of links (contextual, varied anchor-texts, and even relevant) that worked a few months ago aren't working any more for small sites with low TrustFlow. I've encountered atleast 3 sites where in spite of doing a quality on-page work and building limited amounts of grey hat links, I saw almost no improvements on rankings. In fact, one site got penalized heavily. How do you generally proceed with a client site with low TrustFlow when you get, say, only around $200-300 per month for it? Medium competition / local keywords mainly. On the other hand, I've used even raw GSA or a small amount of credits towards private blog network posts from Link Emperor to push some of the guest posts done by clients on authority sites (DA 60+) and they still rank within the first few positions of Google for medium-high competition keywords, bringing in referral traffic to client sites. So, the issue definitely seems to me with TF. Would love to know your opinions about this.
