In order to be able to be listed in search results, your marketplace is indexed by search engines. To improve your listing position, there are a few things you can do to help. These actions are called Search Engine Optimization (or SEO).
SEO in your marketplace
Your Sharetribe marketplace is developed using SEO best practices. Common tags (such as description or title) are automatically added to each page (and built using combinations of your marketplace Name, Slogan and Description). We take care of these so you can focus on improving your social presence and getting more inbound links, for example.
It is also possible to add more meta tags by using Sharetribe's custom script functionality.
Resources to improve your search engine ranking
SEO isn't only about code-related changes. It is also heavily dependant on link building and social media activity. Moz(among others) provides lots of great resources to learn more about SEO to help your with your SEO strategy.
