See word frequency, keyword density, and top 1-word, 2-word, and 3-word phrases. ## How the Keyword Extractor Works This tool uses statistical text analysis to identify the most important terms in your content. Here's the process: 1. **Input your content**, paste text directly or enter a URL. For URLs, the tool fetches the page and strips HTML to get the visible text content. 2. **Tokenization**, the text is broken into individual words and normalized (lowercased, punctuation removed). 3. **Stop word filtering**, common words like "the", "is", "and" are filtered from single-keyword results. They're kept in multi-word phrases where they connect meaningful terms. 4. **N-gram extraction**, the tool counts 1-word keywords, 2-word phrases, and 3-word phrases, calculating the frequency and density of each. ## Why Keyword Extraction Matters for SEO Understanding the keyword composition of your content, and your competitors' content, is fundamental to SEO and content strategy: - **Content audit**, check whether your page actually focuses on the keywords you're targeting. Sometimes content drifts from its intended topic, and keyword extraction reveals the gap. - **Competitor review**, compare repeated language on genuinely comparable pages, then investigate whether any difference reflects user intent rather than copying terms mechanically. - **Repetition checks**, unusually frequent terms can reveal awkward writing, boilerplate or accidental overuse. There is no universal density threshold that guarantees a penalty. - **Content editing**, use recurring 2-word and 3-word phrases as clues about emphasis, then confirm relevance with search demand, intent and subject-matter review. - **Clear language**, descriptive terminology can make a page easier to understand, but phrase frequency alone does not establish topical authority or earn AI citations. Pair this tool with the [Meta Tag Checker](https://webaloha.co/tools/meta-tag-checker/) to ensure your title and description align with your content's actual keywords, and the [Schema Markup Validator](https://webaloha.co/tools/schema-markup-validator/) to verify your structured data supports the same topics. Use the [Keyword Generator](https://webaloha.co/tools/keyword-generator/) to expand from seed terms into 200+ keyword variations for content planning. For overall content depth, the [Website Word Counter](https://webaloha.co/tools/website-word-counter/) shows reading level and readability scores alongside word counts.

If not, your content may need to focus more clearly on the intended topic. - **Review 2-word and 3-word phrases**, these are often the most valuable for SEO. Long-tail phrases like "technical SEO audit" or "website migration checklist" signal specific, high-intent topics. - **Compare with competitors**, run the same extraction on pages that outrank you. Look for phrases they use that you don't, these are potential content gaps. - **Watch for unnatural repetition**, read the affected passages in context. Rephrase only when repetition harms clarity; do not optimize toward a universal percentage. - **Review important page elements**, check whether the title, description and H1 describe the same intent as the body without forcing every repeated phrase into each element. Use the [Meta Tag Checker](https://webaloha.co/tools/meta-tag-checker/) to verify this alignment.

It reports total and unique tokens plus the 30 most frequent repeated one-word, two-word, and three-word results. Every displayed item must occur at least twice, and density is its count divided by the total token count. How do Text mode and URL mode differ? Text mode analyzes what you paste entirely in the browser. URL mode sends the URL to Web Aloha's server, follows redirects, converts the returned HTML to text, and runs a closely matched server-side extraction. What page content does URL mode exclude? Before tokenizing, it removes script, style, nav, header, footer, and noscript blocks, then strips remaining tags. This reduces common boilerplate but can remove meaningful content or retain sidebars, forms, and repeated template text. Does URL mode render JavaScript? No. It analyzes the HTML returned to the server-side GET request. Content added only after client-side rendering, interactions, authentication, or consent may be missing, and bot or CDN responses can differ from your browser. How are stop words and phrases handled? Single-word results exclude a large built-in English stop-word list and terms shorter than three characters. A two-word phrase needs at least one non-stop word, and a three-word phrase needs at least two. The tokenizer is oriented to ASCII letters and numbers. Are the top results automatically good SEO keywords? No. They are frequent strings in the analyzed sample, not search queries from an index. The tool provides no search volume, competition, intent, ranking, conversion, or semantic relevance data, so validate candidates separately. How can I use the output for a content gap review? Compare the same page type across your page and relevant competitors, then investigate meaningful repeated phrases that are absent or overused. Confirm each difference against user intent and source quality before adding language. What happens to my text or URL data? Pasted text stays in your browser. In URL mode, the submitted public URL is sent to Web Aloha's server so it can fetch and parse the page. The endpoint does not include application logic that persists the fetched HTML or report.
