Topical Authority: A 9-Month Case Study

9 months. A niche B2B SaaS site. From page 5 to the top 3, by reorganizing around topical clusters. Here is exactly what we did.

The starting state

• ~120 blog posts, written ad-hoc over 3 years.
• No topical structure. Random keywords, no internal linking strategy.
• Domain rating: 32.
• Average ranking position: 23.

The diagnosis

We mapped every post to a topic cluster. Result: 8 clear clusters, 3 orphaned topics that didn’t fit any cluster, and 24 posts that were thin or duplicate. The site was trying to be an authority on 8 things — and succeeding on none.

The plan

1. Pick the top 5 clusters by commercial intent.
2. Write a 4,000-word pillar for each.
3. Audit every existing post — keep, merge, or rewrite.
4. Build internal links: pillar ↔ spoke, spoke ↔ spoke (where relevant).
5. Publish 2 new spokes per week.
6. Decay-manage quarterly.

The execution

Months 1–2: Wrote the 5 pillars. Audited and merged 60 existing posts into the cluster structure. Deleted 24 thin posts (with 301s to the most relevant pillar).

Months 3–6: Published 2 new spokes/week. Built internal links. Updated Search Console submission for every URL change.

Months 7–9: Decay-managed underperformers. Added sections to top performers based on Search Console queries.

The result

• Average ranking position: 23 → 6.8.
• Organic sessions: +340%.
• Conversions: +180%.
• Domain rating: 32 → 41.

What didn’t work

The orphaned topics (3 clusters we didn’t address) lost rankings. We expected that. We did not expect the homepage to drop — it consolidated signals to the new pillars but lost its own long-tail rankings.

The lesson

Topical authority is a long game. The first 60 days felt like nothing was happening. The 90-day mark was the inflection point. By month 9, the compounding was obvious. Plan for the 90-day mark.
