” The “keyword” <meta> tag used to be important but is basically useless now.”
Quote from Words in a Row
The meta keyword tag
“Don’t make this more than about 250 characters long. Don’t use the same key word more than twice in it. Vary the capitalization. Don’t use all capital letters unless the word is an acronym, like “SEO“, which is short for Search Engine Optimization. Don’t use words in it that don’t show up in the body text on the page. In practical terms, you can delete this keywords meta tag without any consequence. Better not to have a keywords meta tag than one that is filled with keywords that don’t show up on your pages; it can count against you!”
put key words in heading
H1 headings should be used for branding of your site. H2 tags should be used for keywords, to help outline what’s on the page visually. Don’t use more than one H1 tag on a page.
