Text SEO Checker

The Text SEO Checker analyzes a draft against a short list of on-page fundamentals. Paste your article, enter the focus keyword you want the page to rank for, and it grades three things: whether the text reaches a minimum of 300 words, whether the keyword appears in the first paragraph, and whether your keyword density falls in a healthy range.

Density — the keyword's share of total words — is graded against practical thresholds: 0.5% to 2.5% reads as natural optimization, below 0.5% suggests the topic isn't established, and above 3% is flagged as keyword stuffing, which modern search engines actively penalize.

The checklist updates live as you edit, and your draft never leaves your browser.

The useful signal isn't the exact percentage — it's the extremes. If a 1,000-word article about 'standing desks' mentions standing desks three times, search engines may not connect the page to the topic. If it mentions them forty times, the page reads as spam to both algorithms and humans. The healthy middle is where you write naturally and mention the topic as often as a knowledgeable person would.

First-paragraph placement matters for the same reason people skim: search engines weight early content when determining a page's topic, and readers decide in the opening lines whether they're in the right place. If your keyword can't appear naturally in the first paragraph, the page may be about something else.

The 300-word floor is a thin-content guard. Pages below it rarely answer a query fully, and consistently thin pages drag down a site's overall quality assessment.

1. Paste your article or page draft into the content box.

2. Enter your focus keyword — the phrase you want the page to rank for.

3. Review the checklist: word count, first-paragraph placement, and density with its exact percentage.

4. Edit the draft until every check passes, keeping the writing natural — the tool flags stuffing precisely so you don't drift into it.

Input: a 500-word draft with focus keyword 'running shoes' used 6 times, once in the opening paragraph.

Output:

Word Count: 500 (Min 300) ✓ · Keyword in first paragraph ✓ · Density: 1.2% (Optimal) ✓
