The page title is very important, it is evaluated by the search engines and usually appears in the template, or elsewhere in the browser.
Even if it is now assumed that the meta tag "keywords" is no longer evaluated by most search engines, I recommend you to enter at this point reasonable and appropriate keywords.
The keywords have to be separated by commas, with no space after the comma. It should not be too many keywords, 10-20 or less should be sufficient.
The Description is definitely relevant to search engines, and not only for the ranking. It appears in most search engines in the search results, and therefore the description should also be meaningful for people.
It is not enough that the page is found by Google & Co., you have to persuade the visitors even to click on the search result.
The page description should be short and accurate, up to about 250 characters.
