Metatags like "description" and "keywords" are therefore also out of the window for good now
Throw out the "keywords" for sure. By now I doubt that any search engine sees them as anything but attempted spam.
Keep the description. Some search engines, including g###, may choose to display this text if it's a close match for the search terms. Note however that the meta description itself is not indexed-- at least not in g###. So write a nice description for humans.
wmt --definitely bing and google, don't remember yandex-- make a fuss about the meta description. Too long, too short, missing etc. They have nothing to say about meta keywords.
