Inbound links still matter. Despite what you may here from SEO gurus around our industry, the power of high-quality, relevant, and natural inbound links to a dealer's website is still apparent. Google's Matt Cutts acknowledged that in the long run, this may not be the case.
That day, however, is not today.
Google is reportedly in the middle of a 10-year plan to discount links from the search algorithm. The best guess is that they're at about year 5 of this plan, which means that we still have another half-decade to make the adjustment. Many of us already are, but that does not mean that links should not be a part of the overall strategy.
Earn them. Use them appropriately. Avoid anything spammy or unnatural. Focus on incredible content that can get people to link to you rather than schemes or techniques for building them. That's what we do. That's what you should be doing as well.
