'There seems...' 'There seem...'?

Is it always 'There seems...' ? Or we can say 'There seem...' as well.

e.g I made one speech on the subject and I've not referred to it since, and there seems no purpose in doing so.

I referred to the corpus and it returned hits for both 'there seems' and 'there seem'. However, 'there seems' appeared six times more frequently than 'there seem' in the corpus.
This led me to think that 'there seem' is non-standard. The thing that I am not sure of is whether 'there seem' is grammatical.


Thank you

Thanks Mister Micawber.

I didn't know much about 'there' and it's nature so I wasn't sure what to make of the results. Just for your information, here are the links to the search results. 'there seems' 'there seem'

So when do we use 'seem' or 'seems'?


Thank you again

 there constructions show agreement between the verb and the noun which follow there.

There [is / was / seems to be  / appears to be / has to be / should be / could be / must be] a restaurant on this street.

There [are / were / seem to be / appear to be / have to be / should be / could be / must be] hundreds of restaurants on this street.
