Fixes #70 #60 and #1

I checked merging this PR on master, and gatsby develop command shows a blank page in browser. Please let me know what I may be missing.

I have not created .env file with the required values. Can that be an issue, without those values the original code still works, only this PR code does not work

Further investigation shows that only the /, /1, /2 type of pages are blank. All other pages like /about /category etc are working, even the individual blog pages are also working

In my case, it's caused by the SEO component, which requires Facebook as a parameter.
