@abeatrix @kalanchan It's always good to have more keywords in the extension title (<DisplayName> tag), so the extension is more easily discoverable via search engines, and also in the VS Marketplace. Currently, look like the VS Marketplace page is not indexed by search engines, but soon it will be.

Usually, users will search for Visual Studio extension using something like "cody visual studio", and "visual studio" keyword in <DisplayName> tag will help with SEO. This repository has title "Cody for Visual Studio" and it's pretty high in the search results:

Finally, Bing and Duck Duck Go has started indexing our VS Marketplace entry. It's searchable using cody visual studio keywords. Google is a little behind, the repository is in the search results, but VS Marketplace entry is not indexed yet.
