Further to the above I had started this on another forum by mistake.
It is clear I am seeing something very different and wonder if anyone could clarify what I should do please.
See what was said here: http://wordpress.org/support/topic/home-page-title-description-using-yoast?replies=19
To be clear I simply don't know if using Yoast somehow writes my homepage Title and Description?
I am using a theme by Mysite Myway called Infocus where the home page is not in WP admin > Pages.
The home page is in the Theme admin.
There I have set the Home Page Title and Description as I would like it.
In Yoast SEO in Admin I go to the Home tab and what I see is:
Homepage
Title template: %%sitename%% %%page%% %%sep%% %%sitedesc%%
Meta description template:
All I need to know is do I enter my home page stuff here of do I leave this as my Theme has the info already.
Our site is self hosted. WP and Yoast are up to date.
Many thanks :)
