Question

I need to specify multiple copyrights or authors using the <meta> tag. Can I use a <meta> tag with the same name multiple times?

<meta name="copyright" content="Company A" />
<meta name="copyright" content="Company B" />

Will the search engine respect both values? Or, do I need to comma-separate them in one <meta> tag?

Thanks.

Using multiple meta tags with the same name is valid HTML.

But we don’t know how search engines and other readers will interpret them. Either two meta tags will be concatenated or one of them will be ignored/overwritten.

Example: The PHP-function get_meta_tags() will only return the value of the last meta tag if multiple meta tags have an equal name.

To avoid possible problems I would recommend to use a single meta tag:

<meta name="copyright" content="Company A, Company B" />
