What is the metadata of a document?
Document metadata is information attached to a text-based file that may not be visible on the face of the document; documents may also contain supporting elements such as graphic images, photographs, tables and charts, each of which can have its own metadata.
Metadata, as defined by Merriam-Webster, is data that describes other data. As vague as it sounds, when it comes to the Internet, it's anything but. Throughout the Web, metadata is used to describe individual pages on a websites, allowing search engines to understand what each page portrays.
- The meta description is a snippet of up to about 155 characters – a tag in HTML – which summarizes a page's content. Search engines show the meta description in search results mostly when the searched-for phrase is within the description, so optimizing the meta description is crucial for on-page SEO .
- Old habits die hard, and spammers will always fill the meta keywords tag with every word they can think of. As far as Google is concerned, you can use the meta keywords tag all you want. It doesn't hurt anything (or so they say). Bing actually does look at the tag, but they don't use it as a ranking factor.
- Keyword optimization (also known as keyword research) is the act of researching, analyzing and selecting the best keywords to target to drive qualified traffic from search engines to your website.
