Welcome to the Q&A Forum

Hi Ronnel, in my case, the most important of my url (after the home) is missing in all google search, i tried to crawl in many ways but it´s like is not posible to recover, it´s strange becouse i did not heard this can of penalty, that happened the 12 of this month. (sorry for my english, i´m spanish).

UPDATE: i´ve just recover from my situatio prior 12, :), i don´t know how

Thanks very much for the answer, i know about the hreflanf, with sub-folder i think for the principal language you can omitted the sub-folder: example.com for spanish and example.com/en for english, but not so sure if that is good.

I can´t see what cms you are using (not wordpress, drupal or joomla), probably is in a theme template, in a folder call includes, the file the print the header, probably header.php or something, depends the cms or the structure.

The are lots of factors, in google more than 200, and the ones we don´t know, Alvin give you the most important in an express audit, but as i said, there are more then 200, how is made your site, links, age of domain, name of domain, end of domain if is .com or country one. Get all the data that you find in your competitor and try to be better in all ways, like: -Amount of content -Quality of content -Better site on page -Links to your site ...

Fantastic, always when you need to solve this, usually look in the theme directory you are using, it is where it print the content, and like php developers, the folder "includes" is where the header.php, content.php sidebar.php or footer.php are (or similar), is the folder to put this files to not repeat this code again and again in all urls.
