Small business and SEO

If you are a local small business I'd suggest to consider of a Local SEO and mainly take care of SERP in your niche. What blocks do users get in SERP when enter the KW you're targeting?

If it's Google Guarantee, Yelp, Local Pack, Google Merchant ... then you have to be present there too and it can bring more profit to your business then classic SEO. Or maybe it's Fb or even Instagram will work better for you, because your target audience is present there and competition is low .... So, focus on understanding the SERP, your target audience and your best trafic channels and prioritize them.
