Great point C. This is about more than just using the website nicely. It also is about business (Wikitree is paid by ads for which SEO is crucial) and also about attracting people from other countries/in other languages.
I got the request by the team to post my ideas on G2G on improving the use of the AKA/Nickname in SEO (= improve the chance a search machine shows the pages in the first 5 hits), which is much more important than a formal name for many profiles, so here is the text from that e-mail.
An example to describe the problem is here https://www.wikitree.com/wiki/Beij-3
She is world famous in the Netherlands under her stage name, which is put under the nickname or alias. It is also present in the profile.
Hardly anybody knows her by her formal name, which of course is used to build her tree.
Looking at the rendered page, it starts with:
<link rel="canonical" itemprop="url" href="https://www.wikitree.com/wiki/Beij-3"/>
<title>Maria (Beij) Servaes (1919-1998) | WikiTree FREE Family Tree</title>
<meta name="description" content="Is this your ancestor? Explore genealogy for Mary (Beij) Servaes born 1919 Leiden, South Holland, Netherlands died 1998 Horn, Limburg, Netherlands including ancestors + 1 photos + more in the free family tree community."/>
<meta name="keywords" content="family tree of Mary Beij, Mary Servaes genealogy"/>
The description does not take the nick names into account. It is a rather general text asking people to help out.
I reckon most family members of non-notables will also use the nick name (I have examples from my own tree).
Is there a reason not to include the nicknames in the description? Or make the title of the page use the same as is shown under the vitals class div: <div class="VITALS"><span class="large">
Another thing is the apparent trouble Google has with the site map of Wikitree. Do you provide one for them? That would increase the chance that Wikitree is included in the smart page. See eg the google search result for 'Maarten Biesheuvel' (very famous writer in the Netherlands).
generates the smart page
Google/startpage/Bing seaarch on "maarten biesheuvel genealogy" (in English or Dutch) does not show the wikitree page on the first two pages of results. It does show geniweb/openarch/werelate though...
Just my thoughts how Wikitree could be improved to attract more search hits and more non-USA inhabitant.
