What actually keeps an engineering site out of the results?
The cause is rarely keyword difficulty. Six faults account for most invisible manufacturer sites. The first four are content faults rather than technical ones.
NO PROCESS IS NAMED
The home page offers precision engineering solutions. Nobody searches that phrase.
Buyers search five-axis milling, CNC turning, TIG welding or wire erosion. None of those words appear anywhere on the site.
ONE PAGE CARRIES EVERYTHING
A single services page lists eight processes in one paragraph. A page ranks for the thing it is mostly about. A page about eight things is mostly about nothing.
THE SPEC LIVES IN A PDF
The capacity list is a download sitting behind a form. Buyers get it, search engines mostly do not, and nothing on the site states the same facts in plain text.
THE MACHINE LIST IS A PICTURE
The capacity table is a photograph of a printed sheet. A person reads it. A crawler sees an image with no alternative text and moves on.
INDEXATION IS BROKEN
A staging copy is still live and competing with the real site. A noindex tag survived the last rebuild.
The navigation only exists once JavaScript has run. Any one of these removes the site from results without telling anybody.
LOCAL RECORDS HAVE DRIFTED
The firm moved unit and the old address is still live on directories nobody remembers registering. The Business Profile was never claimed. The phone number on the site is the one that was replaced.
※1 Honest caveat: a site can carry every fault above and still take enquiries by phone. Invisible is not the same as failing. This note is about the search channel only.
