I used a well known drop down menu for one of my websites.
From my main navigation. There are about 10 items, that link to a href="#". These items are for example "Community" which opens a drop down leading to forums, members etc. Community itself isn't a clickable item.
But what it means, is that every single page, has 10 links, linking to itself, with irrelevant text.
I didn't realise the issue existed, until I ran an SEO spider tool which showed blue-widgets.html being linked to with tons of irrelevant text.
I don't know for sure, how Google will interpret this.
I'm going to fix it now. Do you think this may have caused damage?
