$20-$50 that seems cheap! Honestly I aim for handpicking the links rather than buying packages that seem too good to be real, the problem with handpicking is the price, they charge $130 for 1 good link with good metrics which is I guess a good price but I don't know how much is gonna impact to my ecommerce page and my budget is not that high so I'm kinda leaning towards those packages haha. Buying small expired domain seem like a good idea, I didn't know abou that!Honestly these days I have better luck buying a handful of handpicked $20-50 niche-related DA15+ website links from Fiverr or here, than any generic link blasting services. I just search "My niche" Da website link, or "My niche" DA guest post and hand-pick through the ones with good metrics. Just make sure you run their site through Semrush or ahrefs , they'll inflate metrics on Fiverr listing pages. Ill also buy small expired domains in the same niche with good link profiles and just 301 them but some people argue the effectiveness of that, seems to help me though. In any case, I cant remember the last time I picked up a generic mass link package or anything that wasn't extremely tailored to my exact niche. At this point I actually get irritated checking the backlink profile of a new site project and seeing ANYTHING that isn't immediately and obviously relevant lol.
Could you suggest me the websites where you are buying those links?
