Hi @Paul_Reading,
Welcome to the wonderful world of SEO.
What you’re seeing, is the result of Google and Bing having different ways of indexing your page.
Bing really likes metatags and structured data - if I look at your site’s source code, only a few meta tags are filled and there’s no structured data (at least not a lot - I didn’t do a thorough analysis, but rather skimmed through the source). If these lack, Bing resorts to plan B: look for header tags. And Bing’s right: you don’t have enough page title headers on your site.
For instance, on your front page, the text “What are we doing?” is not a header, but a paragraph with a really big font. If you replace this with a true header H1, Bing will see it as the page title and index it.
If I scroll further down, I do see headers, which were generated by the Poster stack. These headers are mostly one word sentences, which is something that both Google and Bing don’t like. Headers should be descriptive, so insread of Portland, you could write something like There’s nothing like sailing in Portland!. This sentence contains a few keywords that will trigger both Google and Bing.
Structured data is a bit of a complex subject, but simply put, you’ll list a bit of hidden text that’s just for the search engines that describe what your page is about. In your case, you write articles, so you’d put an Article structured data element in the HEAD section of your pages that contain articles and fill in the information.
Next are meta tags. You have a few meta tags in place, mostly targeted at social media, but are lacking the general ones like page title. Bing cares a lot more about meta tags than Google does, so you could add these to make your site more visible in Bing’s search results.
Google has quite the comprehensive explanation about meta tags here. You add them in the HEAD section of each page.
Cheers,
Erwin
