SEO rulebook

The 19-point SEO rulebook every article has to pass

This is the checklist a careful human editor would run before publishing. TrySEO runs it on every article it writes, scores the result from 0 to 100, and holds back anything that falls short.

Why a rulebook

AI should be held to an editor's standard

Google's spam policies target pages produced at scale mainly to manipulate rankings, with little value for the people reading them. Its guidance is just as clear that using AI is not the problem in itself: what counts is whether the content is helpful, original and made for people.

So the question is never “was this written by AI?”. It is “would a good editor have let this through?”. The rulebook turns that question into 19 checks with plain expectations, so an article is measured instead of assumed to be fine.

  • 19 rules in 5 phases, each with a weight
  • 17 automated checks today, 2 judgment reviews coming
  • Every rule records what was expected, what the article did and how to fix it

Scoring

How the score is worked out

No hidden formula. Each rule is worth its weight, and the result of the check decides how much of that weight the article earns.

Pass

Full credit

The article did what the rule asks. It earns the rule's whole weight.

Warn

Half credit

Close, but not quite: a title that fits yet hides the keyphrase at the end, for example.

Fail

No credit

The rule was missed. The audit records why, and what to change.

Skipped

Left out

A rule that could not be assessed is removed from both sides of the sum, so it neither helps nor hurts.

The overall score

Points earned divided by points available, times 100, rounded. A heavier rule moves the score more than a light one.

Phase scores

The same sum is done for each of the 5 phases, so a weak area cannot hide behind a strong one.

The 75 line

Articles that score under 75 stay drafts for human review. That holds even when auto-publish is switched on.

Straight talk

What the rulebook does not pretend

  • Two rules are waiting for a reviewer. “Matches search intent” and “Beats the competing pages” need judgment, not counting. That review is not built yet, so both are skipped today and left out of the score.
  • Images are yours to add. TrySEO does not generate images. The images rule is there because a long article needs them, and it will keep costing points until the article has them.
  • A first article has nothing to link to. Internal links point at articles you have already published in the project, so that rule only starts passing once you have some.
  • A high score is not a ranking. The rulebook measures on-page quality, the part you control. Nobody can promise where Google will place a page.
