SEO analysis criteria

SEOEngine evaluates each page against a set of on-page checks. Use this page as a reference for what each check means, recommended ranges, and where to edit the matching fields.

Results appear in two places:

  • SEO overview on the Dashboard, grouped by category and filtered by Issues, Improvements, or Good results
  • SEO analytics in the SEO Audit page editor, with separate SEO and Readability scores

SEO overview card on the Dashboard

Select View details on the Dashboard, or open a page in SEO Audit, to review and fix the matching fields.

SEO analytics panel in the SEO Audit editor

These checks help you improve how clear and complete a page is for customers and search engines. They do not guarantee higher rankings.

Before you begin

  • Open a page in SEO Audit, or open SEO overview on the Dashboard.
  • Set a focus keyphrase in Keyword settings in the SEO Audit editor. Without a focus keyphrase, the app cannot calculate a full SEO score for the page.

How results are grouped

Each check can appear as:

  • Issues — problems that need attention, such as a missing focus keyphrase or a meta title that is too long
  • Improvements — areas that work but can still be refined
  • Good results — checks that already meet the recommended range

In SEO Audit, you can also filter pages by SEO score ranges such as Issues (0–49), Improvements (50–84), and Good (85–100).

Checks are organized into the same categories you see in SEO overview.

Search appearance

These checks control how a page may look in search results and whether keyphrases appear in the listing text.

CriteriaWhat it checks
Focus keyphrase in meta titleThe meta title includes an exact match of your focus keyphrase. Placing it near the beginning is preferred.
Focus keyphrase in meta descriptionWords from the focus keyphrase appear about 1–2 times in the meta description.
Related keyphrases in meta titleRelated keyphrases appear at least once in the title or meta title.
Related keyphrase in meta descriptionRelated keyphrases appear at least once in the meta description.
Related keyphrase lengthYou have a useful set of related keyphrases (about 2–4).
Meta title lengthMeta title length is within the recommended range. Aim for about 50–60 characters, and keep it under 60 when possible.
Meta description lengthMeta description length is between 120 and 160 characters.

These checks review page structure, media, and links.

CriteriaWhat it checks
Focus keyphrase in titleThe page or product title (H1) includes an exact match of your focus keyphrase.
Focus keyphrase missing in image alt text / Image alt attributes in contentAt least one image has descriptive alt text, and the focus keyphrase is included when it fits naturally. Keep alt text around 125 characters.
Single H1 tagThe page has one clear H1, usually the page or product title. Multiple H1 tags can make the main topic harder to identify.
Content lengthThe page has enough meaningful content for its type. Product pages often aim for at least 300 words; content pages often aim for at least 800 words.
Internal linksThe content includes at least one link to another page on your store.
External linksThe content includes at least one relevant link to another website when it helps readers.
Images and videosThe page includes supporting media, with descriptive alt text for images.

Content optimization

These checks measure how well your focus keyphrase and related keyphrases are used in the page content and URL.

CriteriaWhat it checks
Focus keyphrase lengthA focus keyphrase is set and kept concise. A length of no more than 4 words is recommended.
Focus keyphrase in introduction / Focus keyphrase missing in introductionThe focus keyphrase appears in the first paragraph, ideally in the first sentence.
Keyword densityFocus keyphrase density stays between about 0.5% and 2.5% of the page text.
Focus keyphrase in URLThe URL slug includes the focus keyphrase words. For short keyphrases (1–2 words), include all words; for longer keyphrases, include more than half.
Related keyphrase densityEach related keyphrase appears at least once in the page content.
URL lengthThe URL stays concise. Shorter URLs (under 60 characters) are easier to read and share.

Readability

These checks measure how easy the page content is to read. Some readability checks need enough text to run; pages with very little content may show Insufficient content first.

CriteriaWhat it checks
Insufficient contentThe page has enough text for a fuller analysis. Aim for more than 300 words of meaningful content.
Sentence lengthMost sentences stay readable. If more than 25% of sentences are longer than 20 words, shorten some of them.
Paragraph lengthParagraphs stay below about 120 words.
Transition wordsTransition words (such as “because”, “therefore”, or “besides”) appear in at least about 30% of sentences.
Consecutive sentencesThe text does not start 3 or more sentences in a row with the same word.
Flesch Reading EaseThe Flesch score indicates how easy the text is to read on a 0–100 scale. Higher scores are easier to read. Prefer shorter sentences and simpler wording.
Subheading distributionLonger content uses subheadings (H2, H3, and similar) to break up the text. For content over about 300 words, aim for a subheading about every 300 words.

Indexing and visibility

These checks control whether search engines can include the page in results and follow its links. Configure them in Advanced settings in the SEO Audit editor.

CriteriaWhat it checks
IndexingWhether search engines are allowed to include the page in search results.
Link followingWhether search engines should follow links on the page.

On the Dashboard, these may appear as Allow indexing in search results, Disallow index in search results, Allow follow, or Disallow follow.

Expected result

After you make changes, save the page in SEO Audit. On the Dashboard, use Re-scan to refresh SEO overview counts for that resource type. If catalog data looks outdated, run Sync now first.

Limitations

  • Checks do not guarantee higher search rankings.
