Meta Title Test100% of top 100 sites passed
  • This webpage is using a title tag with a length of 4 characters. While there's no target number of characters, titles should be descriptive and concise. Using a title tag with less than 20 characters is a missed opportunity since it can be difficult to fit all your targeted keywords in such a short text.
    We recommend using a title with a length between 20 - 60 characters in order to fit Google Search results that have a 600-pixel limit.
Text: 한솔교육
Length: 4 characters
Meta Description Test92% of top 100 sites passed
  • This webpage is not using a meta description tag! You should include this tag in order to provide a brief description of your page which can be used by search engines. Well-written and inviting meta descriptions may also help click-through rates to your site in search engine results.

Most Common Keywords Test
  • There is likely no optimal keyword density (search engine algorithms have evolved beyond keyword density metrics as a significant ranking factor). It can be useful, however, to note which keywords appear most often on your page and if they reflect the intended topic of your page. More importantly, the keywords on your page should appear within natural sounding and grammatically correct copy.
