Hello. I’ve checked your page and it seems you are using Yoast SEO plugin. If everything was set since May or earlier, you did right and Google should at least had visited you once.
Following admin’s link, Site Names in Google Search | Google Search Central | Documentation | Google for Developers gives us more details. The WebSite structured data is the highest priority. You have it already. But somehow Google defaults to the last resort of domain name.
I can’t be really sure. But Google can be instructed for alternatives and there are tips for better names. You can fill in the alternateName property in case your top choice is not selected. You did not need to settle just for one. Also, you rank quite high in SEO. You are the top for Econiweb. However, your desired site name may fall to “Avoid using a generic name.” Econiweb is unique but the words after it if translated are generic. Tantra Yoni Torino got it because it looks short and unique. Also InfinityFree and Tantra Yoni Torino are more concise compared to Econiweb Diseño de páginas web económicas.
Also, if you have Google Webmaster account, have your sitemap uploaded and crawled, so you can check if Google visited your site and if it found problems. No need to be disheartened. Google’s crawl cannot be predicted. Cheers!
