Frequently asked

What is Portfolio53?

Portfolio53 is a web directory that lists approved sites across 22 subject sections. Think of it as a curated print-run of the web — each entry is checked for a live URL and composited into the appropriate section for easy browsing.

Is it free to list my site?

Yes. Submitting a site to Portfolio53 costs nothing. Fill in the add form with your URL, a short description, and your preferred section. Once reviewed and approved, your listing joins the rest of the press run at no charge.

How are sites organised in the directory?

Sites are grouped into 22 subject sections — from Wagering & Games and Computing & Software to Dental Practices and Print Services & Supplies. Within each section, entries are ordered by the date they were added to the directory.

How do I submit a site?

Visit the Add a Site page, enter your full web address and a brief description of what the site offers, then select the section that fits best. Submit the form and the entry will be queued for review before going live.

How long does review take?

Most submissions are reviewed within a few days. The process exists to keep the directory clean — broken links and off-topic entries are filtered out before a site is approved and added to its section.

Can I update or remove my listing?

If your site has moved to a new address or you would like a listing removed, use the contact page to send us the details. We will update or delete the entry from the folio as requested.

What kinds of sites does Portfolio53 accept?

The directory accepts most legitimate websites with a working URL. Sites must have a clear subject that fits at least one of the 22 sections. Placeholder pages, parked domains, and sites without readable content are not approved.

About the Open Index

Portfolio53 is a web directory composed the old-fashioned way: one entry at a time, checked for a live URL, and typeset into a clean, browsable folio. The directory holds 851 approved listings spread across 22 subject sections, from Wagering & Games to Computing & Software. Each section is the equivalent of a press run in a small print shop — deliberate, legible, and built to be useful rather than exhaustive. Visitors can browse by category or use the submission form on the add page to contribute a site that belongs in the listing. The name Portfolio53 reflects the directory's character: a numbered proof, set in type, ready to be consulted. New submissions are reviewed before being added to the approved press run.
