Need Your Opinion..!

First impression is that the Adsense advertisement is badly placed in that white space as it become the focus for the page, which is not desirable. You've also got sidebar adverts so I would keep those and lose the horizontal intrusion.

Apart from the horizontal advertising, the page is quite attractive.

On the bottom RHS there is half of a Google ad showing.

You need more text content. I suggest an intro block of text where you explain what the aims of the site are.

I'm unsure why you have your domain name redirected to the Blogspot sub-domain. Not a good look for SEO. Use your domain name.

I don't understand why there is the English/French mix with some recipes having French title and content and others having English. Confusing!

You have HTML code displayed for Soupe de Poireaux.

You need to add ALT text to all of your images.

Your Home Page title is very poor. Use up to 70 characters wisely.

Your Home Page has no Meta Description. Big error.

There are no Meta keywords. Not a big error but you could have some anyway.

Using upper case letters is "SHOUTING" and not very polite and is also hard to read. Draw attention to body text by using bold text or italics, not upper case.

I don't see English in your language selector. Is it there somewhere?

The Home page is a very large file size. Optimizing your images will help.
