A Meta description is just like an ad-copy hard to write, but good keyword targeted description should match users’ queries and their demands, which would help with the click through rate(CTR). However, it is not a ranking factor. Therefore it is treated only as a summary of the page. However, remember that your Metadata should be written in Chinese, not English.
- Do not stuff keywords
- Each page should have a unique description tags and avoid using the same description tag on all of the pages.
- Do not exceed crawl length, or it will be cropped.
