The following parameters could be set for the archive pages of your site:

• Date archive URLs: how to format the URL of the archive directories
  • Use param: E-g: http://example.com/index.php?m=20191231
  • Use extra-path: E-g: http:/example.com/index.php/2019/12/31/
• Make canonical:
  • 301 redirect to canonical URL when possible: if the detected canonical URL of the archive is different from the current URL, a 301 redirect will be done.
  • Use rel="canonical" whenever necessary: in the case when the 301 redirect is unavailable, a canonical link element is inserted in the page.
  • Use rel="canonical" even when not necessary (self-refering): If this is enabled, the page will include the canonical tag <link rel="canonical" href="http://.../item-slug" /> (pointing to itself).
• Indexing: lets you decide if you want to keep robots away from the archive pages.
• Follow TO: lets you decide if you like robots to follow links in the archive pages.
• Post contents:
  • Post excerpts: display only the excerpt of each post.
  • Standard post contents (stopping at "[teaserbreak]"): display only the teaser of each post.
  • Full post contents (including after "[teaserbreak]"): display the whole content of each post.
• Posts per page: lets you decide how many posts would you like to display on each page of the directory.
• Archive directory: check to add a <meta name="robots" content="NOINDEX, FOLLOW"> tag to the headline of the archives directory page (disp = arcdir). The NOINDEX parameter aims to prevent search engine robots to index the page that contains it, and the FOLLOW tells search engines that it may follow any of the links contained on the page.
