SEO Checklist
Most SEO checklists are ordered by category, which puts trivial items next to fatal ones. This one is ordered by consequence: a page that is not indexable cannot be rescued by anything below it, and a page that misreads intent will not rank however well it is optimised.
Last reviewed: August 2026
In order of what actually costs you
- 1. Is it indexable? No stray noindex, no canonical pointing elsewhere, not blocked. A wrong canonical removes the page entirely — the highest-consequence failure and the easiest to miss.
- 2. Does it match intent? Open the results for your target query. If the ranking pages are a different format, yours will not rank.
- 3. Does it answer in the first 40 words? The strongest single content signal for both readers and answer engines.
- 4. Does the title fit and earn the click? Under roughly 62 rendered characters, and stating the benefit rather than the category.
- 5. Is there anything here that is not elsewhere? If not, the page has no reason to outrank what exists.
- 6. Do internal links point at it? A page nothing links to is found late or not at all.
- 7. Is the structured data valid? Increasingly what decides whether you get quoted rather than just ranked.
- 8. Then the details. Alt text, image weight, Core Web Vitals. Real, but tiebreakers rather than causes.
Before publishing anything
| Check | Fails when | Cost of missing it |
|---|---|---|
| Indexable | noindex or wrong canonical | Total — the page does not exist |
| Intent match | Format differs from what ranks | High — good page, no rankings |
| Answer up front | Buried below context | High — lost to a faster answer |
| No self-competition | Another of your pages targets it | Medium — you split your own signals |
| Internal links in | Nothing links to it | Medium — slow or no discovery |
| Valid schema | Invalid or missing JSON-LD | Low to medium — no rich result |
On-page, technical and off-page — in the order that pays
How Gixo Quill handles this
Several of these are deterministic and Quill checks them without a model: answer extractability tests whether the question is answered up front, the overlap checker catches self-competition, and the content health check covers structure and readability.
Frequently asked questions
What should an SEO checklist cover first?
Indexability. A stray noindex or a canonical pointing elsewhere removes the page from search entirely, which outweighs every other item on any checklist.
How do I check search intent?
Open the results for your target query and look at what ranks. If they are all comparisons and you wrote a guide, the format is wrong regardless of quality.
How long should a page title be?
Under about 62 rendered characters, or it gets cut in the search result — usually at the point where the differentiator sits.
Do Core Web Vitals belong on the checklist?
Yes, near the bottom. They are a genuine tiebreaker between comparable pages, but they will not rescue a page that is not indexed or misreads intent.
What is the most commonly missed item?
Internal links pointing at the new page. It is invisible in any on-page audit and it is why good pages sometimes take months to get found.
What belongs on an on-page SEO checklist?
Title, the answer in the first 40 words, heading structure, internal links pointing in, and valid schema. On-page is the part you fully control and the part that shows up fastest, which is why it is worth working through before anything off-page.
What is off-page SEO, and where does it belong?
Links and mentions earned from other sites. It is the slowest and least controllable lever, so it belongs last — pointing links at a page that is not indexable or misreads intent wastes them.
Are SEO best practices the same as a checklist?
No, and conflating them is why checklists get padded. Best practices are the habits worth keeping; a checklist is an ordered set of failures to rule out before publishing. Practices worth following that fix nothing on a given page do not belong on it.
Does passing more checklist items mean better rankings?
No. The items are not equal and the score is misleading — a page failing only indexability still earns nothing while scoring highly. Work the order, not the count.
