I do not know if themes affect the Page Rank of a certain blog. But for sure, SEO does, and since there are travel blog free templates and themes which are SEO-optimized already, I could somehow say that perhaps blog templates and themes do affect ones Page Rank.
This is the third travel blog template that I’ve installed on this blog. And hopefully, this will be the last as well. However, for the past Google Page Rank updates, this blog experienced negative affectation – its Page Rank dropped from “2” to “1”. For some, it’s just a one-level drop though, but for me, it’s something to worry of. I am afraid it might totally drop to “0” then.
At this moment in time, I want to create free templates again for this and to my to my other blogs. I want to use other template base themes other than this that is basically SEO-friendly. The base theme of this blog, accordingly, is already SEO-optimized, but maybe I just don’t know how to use it.
