I suggest you use:
1.bookmarking sites list
2.social bookmarking list
They are both fairly low competition and steady search trends.

Here is a screenshot:

 

You may use Free bookmarking sites, social bookmarking sites and high pr bookmarking sites..

 

I totally agree with dannbkk, but most of them are highly competitive. But we might look forward with other possible keywords with low competition too, especially long-tailed keywords.
