I have read those links you are recommending about microformat and w3.org but since I don’t have a background in coding, it makes little sense to me.
What i need to know is the following.
Google has to started to index my webbpage, and according to the different functions on google webbmaster tool, i do get different results.
What i need to know regarding the function structured data / hatom, is marking 7 objects (i have 7 pages) with faults. Mainly its saying that each page is missing Author and the function “updated”. Each page has been written by Admin. Do i need to care about this, and will it influence SEO performance?
