什麼是關鍵字密度分析工具?

關鍵字密度是指目標關鍵字相對於頁面總字數的占比,以百分比表示。現代 SEO 不會獎勵關鍵字堆砌:Google 的演算法能夠偵測出不自然的密度並加以懲罰。理想區間通常在主關鍵字的 0.5% 到 2% 之間。本工具會忽略常見的停用詞,並顯示出現頻率最高的 30 個詞,幫助你發現那些不經意間被過度使用的片語。

常見使用場景

  • Checking a blog post before publishing to see whether your target keyword actually appears prominently.

  • Catching unintentional repetition, such as a brand name or filler word you leaned on too heavily.

  • Comparing two drafts to see which one foregrounds your main topic more clearly.

  • Quickly profiling a competitor's article you pasted in, to see which terms they emphasize.

  • Tightening product descriptions where a single word has crept in far more often than intended.

  • Teaching writing or SEO basics by showing live how word frequency shifts as text is edited.

常見問題

理想的關鍵字密度是多少?
沒有神奇的數字。請為你的讀者自然地寫作。如果你的主關鍵字出現的頻率在 0.5% 到 2% 之間,通常就沒問題。
