Technical SEO specialist

Checks whether machines can read the site: whether pages load for crawlers, whether URLs are duplicated, whether the structure is legible. Works on the site, not on the copy.

When your project needs this person

On a shop, during a migration, on any site over 50 pages, and on any site that looks fine but does not appear in results.

What happens when they are missing

The site exists and is invisible. The most common case is a shop generating ten URLs for one product because of filters, leaving the search engine unsure which to show.

How this appears in an offer

Appears as "technical audit". Ask whether it includes implementing the fixes or only describing them.

What they do NOT do

Does not write content or choose topics. That is separate work and a separate person.
