Credibility concern recorded. The source reference remains available for verification and correction.
SEO Cartel offers bulk backlinks, guest posts, and sitewide cross-links under a domain styled as Isabel Allende courses.
- For
- SEO operators seeking bulk link placements
- Worth noticing
- The page says Cloudflare blocks user agents containing “Google,” while Nginx returns 520 for matching requests.
Field notes
The offer distinguishes guest posts—described as relevant articles published on sites in its database—from sitewide placements in footers, sidebars, or templates. Its table gives four volume bands, with listed rates declining from $1.00 to $0.30 per link. The page also claims to block Google user agents through Cloudflare and Nginx; those technical and performance claims are self-reported.
