Affiliate Network: Scaling Content Across 12 Sites (+184%)

Starting situation

Affiliate with 12 sites in the portfolio (4 EN-UK, 3 DE, 2 IT, 2 ES, 1 EN-AU). All sites competed with each other for 60% of total requests - classic portfolio cannibalization. Total traffic ≈85k/month, plateau for the last 4 months. The content team produced pages without coordination - duplication of topics between sites.

What did you do

• Month 1: cross-site cannibalization audit - 340 overlap points were identified between portfolio sites in one GEO.
• Month 1-2: brand mapping - each of the 12 sites received its own niche: one for slots, another for live, the third for mobile-first, etc. Redistribution of existing content by niche.
• Months 2-6: a single content-pipeline with output division by site and semantic differentiation (one topic - but different focus for different sites).
• Month 4-8: Coordinated link building with division into niches without footprint between portfolio sites.

Result

• Cumulative portfolio traffic: +184% (from 85k to ≈241k/month)
• Cannibalization reduced from 60% to 12% in overlap niches
• Average portfolio ranking: position 11 → position 5
• The cost of one page of content is 2.4 times lower due to a single pipeline

What is important to understand

The main challenge in multi-brand SEO is not “how to promote more sites,” but “how to avoid internal competition.” We spent the first 2 months exclusively on strategy (without production), which at first looked strange to the client, but provided the basis for scaling.
