Good reasons to write

  • Technical questions about an article — I answer directly, or turn good questions into new posts.
  • Corrections — wrong information, outdated numbers, broken links, tools misbehaving. These reports are genuinely welcome.
  • Hiring us for professional web design or SEO — delivered through GPWebMedia.
  • Content collaboration — if you have a real case study with numbers you want to share.
  • Copyright concerns — if you believe content here infringes your rights.

What I decline

  • Paid guest posts or selling link placements.
  • Link exchange schemes.
  • Reviewing products I have never used.

I decline these to keep the site trustworthy.
