Google adjusted how it treats paid links last month and a number of small businesses stopped existing.
Not businesses that sold links, though those had a bad month too. Businesses that had bought them, on the advice of a consultant, as a legitimate-sounding service with an invoice and a monthly retainer, and who woke up to find their site several pages further down than it had been on Friday.
This is a strange industry and it is worth being honest about why.
Search optimisation is a profession built on inferring the behaviour of a system nobody outside one company is allowed to see, which changes without notice, and which is actively maintained by people whose job includes defeating the inferences. You cannot test against it properly. You cannot get a straight answer about it. And the system’s owner has a permanent structural interest in your work not being effective, because the moment ranking becomes purchasable the results stop being worth using and the whole business collapses.
So the practitioner sells a service that the counterparty is committed to breaking. There is no other trade quite like it.
What makes it worse is that the honest version of the job is unsellable. Nearly everything that reliably helps is dull. Put a sensible title on the page. Make the URL describe what is on it. Do not hide your text in an image. Let the thing load quickly. Write something a person would want to read and give other people a reason to link to it without being paid.
Try charging four thousand a month for that list. The client hears their own web developer’s job description and asks what they are paying for.
So the industry drifts toward things that sound technical and proprietary, because those are the things that justify a retainer. Directory submissions. Keyword density targets. Reciprocal link schemes. Article spinning. Purchased links from sites that exist only to sell links. Each one is a tactic that works for a while, gets abused, gets detected, and then gets penalised, at which point the consultant explains that the algorithm changed and proposes a recovery engagement.
The clients most exposed to this are small operations without a technical person to ask. A restaurant owner or a plumber cannot evaluate any of it. They are buying on trust, and the failure arrives months later, and the diagnosis requires exactly the expertise they lacked in the first place.
I do not think the whole field is fraudulent. Plenty of people in it are doing careful, useful work on site structure and content, and they are the ones whose clients did not get hit last month.
But the incentive gradient runs the wrong way, and it will keep running that way as long as the boring correct answer is impossible to invoice for.
