On-site SEO or Off-site SEO: which is the best?

In the light of current updates in Google's algorithms which should one focus on more?
On-site SEO: ie, optimizing your site
OR
Off-site SEO: ie, building links

 

Focus on both, it's not that hard.

 

^I agree completely^

 

If you know what keywords to target it is not hard to optimize the titles,meta tags, content and h1 tags on your site.

Once you have done this you should concentrate on the offsite techniques to build a variety of homepage and deep links with different anchor text.

Target relevant sites first and then some non relevant sites as well.

 

Thanks for the replies.
On-site SEO is quite easy.
But I find getting links difficult, unless you are into buying links.
Should I go for reciprocal linking or not as many people now advise against it?

 

I'd rather buy links than go the reciprocal route.
