Building Convertify in Public Week 10: PDF Cluster + Blog Launch

Week 10 of building Convertify (convertifyapp.net)
in public.

What I shipped

PDF cluster 4 new pages:

  • /heic-to-pdf (33,100 searches/mo, KD 36)
  • /pdf-to-png (74,000 searches/mo, KD 42)
  • /pdf-to-jpg (90,500 searches/mo, KD 86)
  • /png-to-pdf (3,600 searches/mo, KD 43)

Backend (poppler) was already there from the
images-to-pdf feature — pure content work.

Blog 0 to 3 posts in one week:

  • "What Are HEIC Files?" KD 20, lowest KD across all 1,192 keywords in my strategy
  • "How to Convert PDF to JPG 5 Methods"
  • "AVIF vs WebP vs HEIC 2026"

Full SEO infrastructure from day one: BlogPosting
schema, BreadcrumbList, OG images, canonical,
sitemap updated.

Numbers

Metric T9 T10
Indexed pages 75 100 (+25) 🔥
Impressions (3mo) 509 520
Avg position 40.1 40

Unexpected: chatgpt.com sent 13 sessions this
month. Blog posts are getting picked up by AI.

First blog post got 18 views in week 1 small
but it's a start.

What I missed

  • Internal linking blog <-> converter pages (P0 for next week without this, blog traffic doesn't convert)
  • Showoff Saturday post deleted again

Next week

  • Internal linking blog <-> converter pages
  • Blog post #3

Week 1–10 recap: 0 -> 100 indexed pages,
0 -> 520 impressions, 0 -> 3 blog posts.
