Choosing SEO content writing on published evidence

Content writing is the easiest marketing service to buy badly, because the deliverable looks the same whether it took four hours of research or four minutes of generation. Word count is the metric everyone quotes and the one that predicts results least well. What actually separates providers is the research underneath the draft: whether they picked the query from measured demand, whether the writer understands the trade well enough to say something a buyer could not get from the first result, and whether anyone checks the claims. This index lists writing providers on what they publish about price, specialism and named work, so you can compare on evidence instead of on samples chosen to flatter.

How to vet an SEO content provider

  1. Ask where the topic comes from. A provider should be able to say which query a piece targets, what its measured demand is, and why that query is winnable for your site. If topics arrive from a content calendar with no query attached, you are buying volume rather than visibility, and the pieces will compete with each other rather than with your competitors.
  2. Read Google's own bar for the work. Google's guidance on helpful, reliable, people-first content lists the self assessment questions it wants a page to pass, including whether the content offers original information and whether it is written by someone with demonstrable expertise. Ask a provider to walk one sample through those questions rather than through a keyword density tool.
  3. Establish the AI position in writing. Google has stated that its focus is on quality of content rather than how it is produced, and that using automation to manipulate rankings violates its spam policies. So the question is not whether the provider uses tools, it is who does the research, who verifies the facts, and who is accountable for the claims. Get that answer in the contract.
  4. Check the revision and fact-check terms. Ask how many revision rounds are included, who verifies statistics and links, and what happens when a subject matter expert on your side disagrees with a draft. Providers that price purely per word usually treat revisions as scope creep, which is where the working relationship breaks down in month three.

What separates a page that ranks from a page that exists

Three things, in order. The first is that the page is aimed at a query real people type, chosen before the writing starts. A well written article aimed at nothing is a well written article nobody finds. The second is that it says something the existing results do not, whether that is original data, direct experience, or simply a clearer answer to the question actually being asked. Google's documentation asks whether content provides original information, reporting or analysis, and whether it offers substantial value compared to other pages in results.

The third is that a person who knows the subject stands behind it. Google's spam policies name scaled content abuse, meaning many pages generated primarily to manipulate rankings rather than to help users, and warn that violating sites may rank lower or not appear at all. That is now the main risk in cheap content: not that a page is badly written, but that it is one of a thousand indistinguishable pages published in a month.

What moves the price of writing

Subject difficulty is the biggest driver. General business copy is a commodity. Regulated fields such as finance, health, and law require writers who can navigate the rules and an approval loop on your side, and both add cost. Technical fields require someone who can interview an engineer without wasting the engineer's hour. The gap between a general writer and a specialist is often a multiple, and in regulated categories it is the difference between publishable and unusable.

Research depth is the second driver, and it is what a per word price hides. A piece built on original interviews, proprietary data or a genuine test costs several times a piece assembled from the first page of results, and it is the only kind that reliably earns links. The third driver is process: a provider that includes query research, an outline approved before drafting, an editorial pass and an SEO review is selling four jobs, and its price should be compared against the cost of doing the other three in house.

Questions people actually ask

How much content does a site actually need?
Fewer, better pages beat volume in almost every case. A site that covers its commercial queries thoroughly, each with a page that genuinely answers the question, outperforms a site with hundreds of near duplicate posts. Volume only helps when each additional page targets demand that is real and currently unserved on your site.
Does Google penalise AI-written content?
Google has said its focus is on the quality of content rather than how it is produced, while its spam policies name scaled content abuse, meaning pages generated primarily to manipulate rankings. In practice, the accountable question is whether a knowledgeable person researched, verified and stands behind the page.
Should I pay per word or per project?
Per project, wherever possible. Per word pricing rewards length and penalises the editing that makes a piece useful, and it makes research invisible in the invoice. A project price tied to a defined deliverable, including query research and revisions, is easier to audit and produces a better argument about scope.
How long before new content ranks?
Google's starter guide notes that some changes take effect within hours while others take several months, and it suggests waiting a few weeks before judging a change. For a new page on an established site, a few weeks is often enough to see direction. On a new domain, expect two quarters before the pattern is readable.
