I have been working with these campaigns for six months and I'm ready to share my experience. I'll start with the drawbacks. In some cases, several links would hang (as if they were forgotten to be added), and I had to contact technical support. After reaching out, they add the links almost instantly, but I still don't understand the reason for this. Also, you can't check the indexing of the links (there are no corresponding buttons), which creates inconveniences, and it would be nice to fix this. I have to use other tools to check indexing. These are probably the most significant downsides I would like to point out. Now for the positives... The links really look natural; they are definitely not SEO links. There is no rental fee. The guarantee on the links is impressive; I haven't seen such warranty conditions anywhere else. The price is quite reasonable for the market. The post texts look good; you can't pick at them, as if they were written by a real person. The effect of the links is evident; they are definitely not useless, but the site doesn't start to grow in search immediately — usually, changes become noticeable after 2.5-3 months. I would recommend this service to friends, especially beginners in SEO who don't want to delve into website promotion.
