Some search engines punish sites that use the same meta tags on different pages. Uncheck this option if you want to suppress the repetition of the same meta tags on pages that use the pager - if unchecked, Drupal will only display the meta tags for the first page and not for subsequent pages. If unsure, select this option.
Use front page meta tags
Check this option if you want to use the meta tags for the front page even if the default front page specified is a view, panel or node - in this case, the meta tags specified for the view, panel or node will be ignored. If you want to use the meta tags of the view, panel or node instead, uncheck this option. If unsure, select this option and specify the meta tags you want on the meta tags for the front page.
