Welcome to the Q&A Forum

Absolutely agree with Egol. This might not help with the SEO per se, but such a big SEO factor is how happy people are on the page itself. You might find by adding important bullets that you retain someone for longer, make them want to read further and then go on to make a purchase. Make the pages as good as is possible. -Andy

Hi there - The simplest thing to do is to: choose a url variant (either with or without /) and apply it consistently across the site. say you choose the "without /" version. Redirect all "with /" versions to the without version. make sure the rel=canonical of each page points to the variant you choose (either the with or without traling slash variant). when linking to a page on your site (from a banner for example) try to link to the variant you choose, otherwise Googlebot has to follow a url redirect unnecessarily, which is an inefficient use of your crawl budget. I hope this is clear. Thanks!
