I, personally, am so thankful of that fact.
Now, for those who actually do the work and write blogs about their subjects, you can still get the social media boosts without having to spam social media sites. Most SEOs know that link juice travels down - it goes through one link and onto the next. That's a simplified explanation, but an important one to note nonetheless.
So, instead of submitting Used Cars New Hampshire to a social media site, it is better to have a blog post that links to it, then submit the blog post. As long as the post itself is informative and not spammy, you should be able to get some link juice to flow to your sites or clients.
Like I said, simplified. There is a lot more that goes into it than that. Still, it's a start. Enjoy!
