For years, gurus have argued about the "Halo Effect" of PPC. In 2026, with the A10 algorithm update, the answer is no longer ambiguous. It is mathematical.

The Hypothesis

We believe that Exact Match PPC sales contribute higher relevance signals to the A10 algorithm than Broad or Phrase match sales, resulting in faster organic ranking for those specific keywords.

The Data

We tracked 50 product launches over a 90-day period. We split them into two groups:

  • Group A: Auto + Broad Campaigns only.
  • Group B: Aggressive Exact Match Campaigns aimed at Top 10 Search Volume keywords.
Metric (Day 90) Group A (Broad) Group B (Exact)
Avg Organic Rank Page 2 (#24) Page 1 (#4)
Organic Sales % 35% 68%
ACOS 28% 32% (Higher initially)

The Conclusion

The data is clear. While Group A had a lower ACOS initially, they failed to stick on Page 1. Group B sacrificed early profitability for a massive gain in Organic Ranking.

The "Halo Effect" is strongest when you prove to Amazon that you convert for a specific, high-intent query.

Want these results?

We use the "Group B" Exact Match strategy for all our clients. It costs more upfront, but it builds an asset.
