Growth systems that pay for themselves.

ChatGPT, Claude, Perplexity and Google all send crawlers. Almost nobody checks what those crawlers were actually given. I built CrawlCheck because I needed the answer for my own sites and no tool would tell me.

It sends fifteen client identities to a homepage from one address inside one second and keeps every reply — status, bytes, content type, cache header. Same second, same address, so a difference between them is the edge deciding, not the internet being busy. The most common serious finding so far was a file returning 200 to every crawler while serving a verification page instead of the content.

The scan is free and stays free. What costs money is the record: a dated series that says what changed, which a single fetch can never produce after the fact.

Tree, fencing, concrete, excavation, landscaping. I own the domains, the rankings and the phone numbers; licensed crews do the work and get paid for it. This is not a client roster — it is a portfolio.

Lead generation is the half I am good at and the half that is cheap to replicate. Capacity is what decides how much of it turns into money. A ranked site attached to a crew that answers the phone is worth many times the same site attached to nobody, and I have run both.

A specialty breeder of reptiles and invertebrates raised in bioactive setups. Low volume, high value, mostly referred — the sort of trade where a buyer is paying as much for the record as for the animal.

My photographs illustrate the Wikipedia articles for Gonatodes daudini and Cnemaspis chanthaburiensis, and the daudini infobox credits Terrarium Station as a captive-breeding source. That is a third-party page I do not control, which is exactly why it is worth more than anything I could write about myself.

The product is a working terrarium, not just the animal in it. Every listing says whether the photograph is the animal you are buying or a representative of the group.

An F-number means nothing unless the chain behind it exists. Most of this trade runs on a claim in a forum post: someone says an animal is F3 and there is no way on earth to check it.

SpeciesVault gives every animal an accession number, links sire and dam as records rather than as text, and derives the generation by walking that chain. A number that cannot be derived renders differently and says so — asserted by the keeper, chain not verifiable. The seller records the transfer at the point of sale, because a buyer\'s claim about parentage is unverifiable by construction.

It exports Darwin Core, which means an institution can read it without asking me for anything.
