Why Use a Simulator

Editors and writers benefit from a single surface that consolidates common on‑page checks. Instead of scanning a draft in multiple places, the simulator assembles signals that often correlate with clear, scannable pages. The output is not a search engine prediction, but a drafting compass for everyday quality assurance.

Because the tool runs locally, it fits into fast feedback loops. Writers paste a draft, tap analyze, and scan the breakdown. The score and suggestions help decide whether the draft is good to publish or needs another quick pass.

Signals the Simulator Weighs

• Keyword Presence: Checks for the target term across title, meta description, H2s, and body.
• Keyword Density: Looks for a practical range to avoid underuse or overuse in the body text.
• Synonyms: Detects at least one related term to improve topical breadth.
• Title Length: Encourages concise titles that typically display well.
• Meta Description Length: Aims for a range that commonly fits result snippets.
• URL Slug Format: Verifies clean, hyphenated lowercase slugs.
• H2 Structure: Looks for at least two descriptive H2s with reasonable length.
• Readability Proxy: Uses average words per sentence as a quick legibility check.
• Passive Voice Proxy: Flags frequent be‑verb + past participle patterns.
• Links Mix: Encourages both internal and external references.
• Images with Alt: Confirms descriptive alt text is present.
• Word Count vs Goal: Compares length with a selectable baseline.
• Paragraph Depth: Looks for multiple content blocks to support scanning.
• Repetition Penalty: Reduces the score when identical 4‑grams repeat excessively.

These checks come together to form a balanced overview of basic on‑page hygiene. The intent is to support editorial judgment, not to replace it.

Understanding the Score

The score ranges from 0 to 100. High scores indicate the draft satisfies most weighted checks, while lower scores point to specific areas that need attention. The breakdown lists each check with an OK, PARTIAL, or MISS state, along with the weight contributed to the total.

The most actionable part is the suggestion list. Each item corresponds to a missed check so editors can fix the gaps quickly—add an internal link, shorten a title, or include alt text for an image.

Keyword Use and Synonyms

Keyword presence across multiple fields helps align the draft with its stated topic. The simulator looks for the target term in the title, description, H2s, and body. It also checks for at least one synonym or related term, which often improves clarity and coverage.

For density, a practical band keeps the draft natural and avoids repetition. When density is too low, the topic may feel underdeveloped; when it is too high, the writing can read unnaturally.

Headings, Links, and Images

Clear H2s provide structure and create scanning points for readers. The simulator expects at least two H2s under typical conditions, each short enough to read easily. Links are assessed as a mix of internal and external references, signaling both connective structure and helpful resources.

Images with alt text are encouraged so that visual elements contribute meaningful context. The tool checks that at least one image includes alt text and counts more as they appear.

Readability and Flow

The readability proxy uses average words per sentence as a light indicator. While it doesn’t replace full readability suites, it reveals when sentences grow too long and suggests a tighter rhythm. Pairing this with paragraph depth gives a practical sense of pacing and scanability.

A repetition penalty addresses overuse of identical phrasing. When the same sequence of words appears too often, the score tapers to encourage rephrasing and fresher language.

From Draft to Decision in Minutes

A common flow starts by pasting the draft and adding a target keyword and synonyms. After analysis, the breakdown and suggestions highlight quick wins. Editors typically adjust the title and description, add or rename H2s, balance internal and external links, and include one or two images with descriptive alt.

Running the analysis again surfaces the improvement. This loop takes minutes and helps maintain consistency across a multi‑author content program.

Using Word Goals and Ranges

Word goals provide a simple baseline for coverage. The simulator compares current length with a selected target such as 1000+ or 1500+. The intent isn’t to inflate word count for its own sake, but to verify that core sections and examples fit the intended scope.

Paired with H2 checks and link mix, length becomes a signal of completeness rather than a fixed requirement. Teams can adjust the goal according to the topic and audience.

Local Processing, Fast Feedback

Because the simulator runs fully in the browser, it avoids network delays and keeps drafts private. This suits early versions, embargoed material, and client work. The instant feedback encourages frequent small improvements rather than infrequent large rewrites.

The interface focuses on clarity: a score ring, a checklist with weights, and a suggestion list. Together, they make the next steps unambiguous for both writers and editors.
