Is it possible to make your jotform form searchable by search engines like Google, Yahoo or Ask? Is there any settings?

If the form is linked from a public page, a search engine bot can find it and list it. Forms are SEO optimized but there are no explicit way to increase SEO by adding some metadata tags inside of the form.

However you can embed your form to your website and then optimize SEO of your website. This guide can help you with that: http://www.mtu.edu/umc/services/web/seo/
