My github.io cannot be searched by google

[TianjiaoLuo]

I tried to build my personal homepage modified from this repo. However, I found my github.io cannot be searched by google. I tried to add my github.io to google console and after half a year it hasn't finished indexing. Until now, my personal homepage is not searchable by google but can be searched by bing.

Is there any way to make my homepage searchable by Google?
