The SEO Settings on the Jimdo site are the best way to have most of the site optimized for search engines.
These will influence the way the site is displayed and will help search engines understand your sites contents so it can be displayed even if no keywords are met.
Since keywords are only indirectly used, it is very important to use a few words that a potential visitor will most likely type into a search engine.
As explained in "SEO- Contents", these words should be used throughout the site, but they can also be used in the SEO settings panel.
To do so open SEO > Settings > SEO.
First, select the Website tab and fill in your Site Title with the name of your business or website. This will be the title displayed in the search engines and also the title displayed in the tab of your browser, like here:
In the Pages tab you can enter a Page Title and Page Description for each page of your website.
These will also be displayed in the tabs of browsers, according to the page name.
In any case, the descriptions should be written using natural language. A list of keywords will neither look good to the visitors nor will Google and Co. be "pleased" about it, which might result in a lower search result ranking of the site.

You will also find the Advanced Settings Tab here, which is available only for JimdoBusiness users. It allows you to set three tags, NoIndex, NoArchive and NoFollow.
NoIndex This tag is used to mark all pages you do not want to be indexed so they will not show up in the search engine results.
NoArchive This tag prevents google from saving an archived copy of your site so it cannot be accessed later on via waybackmachine (https://archive.org/web/) or similar services.
NoFollow Setting this link will stop crawlers from following any links on the page so the connection between two pages will not reflect in the search results.
