|The term "keywords" is used in different contexts, for different purposes:
1. Keywords in DC or GLS metadata: keywords are words or phrases summarizing an aspect of the data set or the specific website page that help pages to be identified, found, tracked and reused.
2. Keywords in HTML content: these enable pages to get high ranking in search results. Sometimes an HTML keyword metatag is a useful supplement, but Search Engines are now weighting actual content much higher than metadata keywords.
In both cases, the keywords need to be given more weight statistically for SEO by using the keywords throughout the page's text.
