Sorry , But this is a poorly worded survey!
The options are not comparable, For example Facebook and linkedin are Examples of S.E.O (which is another option)
They are also places to advertise so could be considered a tick in the "where to advertise" box. There will be a bias towards the Broader Headings -SEO and Where to Advertise.
|Good Comments though !
thanks for the comments, but facebook and linkedin are totally different platforms, each can be used for SEO thats obvious, this was not the reason for the poll, but I too understand what you mean if you don't read it the same as me.
the reason for adding a poll is I know there are 10 times the amount of viewers that will not comment on these posts or any for that matter, they just look.
Adding a poll allows them to add to it with a click of a buttom anonymously and without the lions thats are waiting to jump on there back for putting anything that they can get there claws into.
I'm finding this poll useful also the comments being made

Thanks for your post

Ian
