For me a few things come to mind
- What is the website product ??
- Does the Log reflect the website Product
When creating a logo you do not want the bacckgroun being busy.
What is the main colours of your site and perhaps the log should be produced with that colour as a background
A back ground that is busy will detract from the logo unless the background is representative.
I cannot make the image you have posted any bigger so cannot make out what the text is within the logo
This is a consideration as well, if there is text as part of the logo then it needs to be clear and concise, easily read at logo size.
Out of the ones in the image above the bottom row, 2nd from right - provided the background of this can be merged seamlessly into your website background otherwise it just looks like a square which in my opinion is a bit clunky
