Such packages might look cheap and attractive, but often the real cost is hidden — weak domains, deindexed sites, irrelevant profiles, or links that don’t stick.
Test with a small batch first, watch what actually happens (do the links stay live? any drops in rankings?).
Ultimately, what matters isn’t just the number of backlinks advertised, but whether they’re on clean, relevant sites and whether your linking strategy aligns with other SEO fundamentals.
Proceed cautiously and manage risk accordingly.
