Aviva Directory - Worth submitting !
Webmasters always aim to gain High Search Engine Ranking Positions (SERPs) for their websites, which can be a directory/blog/forum or any site. And for this lot of incoming/inbound links are necessary.
And the easiest way to get such inbound links is to submit your url to directories – Not any directory, only to Best Web Directories like Aviva Directory.
Aviva Web Directory 
is rocking in the directory world and is considered one of the strong directories. You can get listed on this directory if your site qualifies their submission guidelines. Its currently having Page Strength 7 and Page Rank 6 with lot of high PR category pages.
So you will definitely get some high PR and SERPs if you are lucky to get listed on Aviva. So no need to hire any costly SEO services 
if you can do that easily on your own and at cheap.
The gains from directories are not so high.. if you are aiming for great PR/SERPS you need better strategies.
I disagree. Google just ignores links from directories. It is better to get links from quality sites.
