The world is mobile today. Most people are searching on Google using a mobile device. The desktop version of a site might be difficult to view and use on a mobile device. As a result, having a mobile ready site is critical to your online presence. In fact, starting in late 2016, Google has begun experiments to primarily use the mobile version of a site's content42 for ranking, parsing structured data, and generating snippets.
Reviews are important to your small business because having reviews—especially positive reviews—is a ranking factor on Google. People are also more likely to click and visit your business if it’s listed with a lot of good reviews. To get reviews, start by asking your loyal customers and even your staff to leave reviews on major sites such as Google and Yelp.
If you are using Responsive Web Design, use meta name="viewport" tag to tell the browser how to adjust the content. If you use Dynamic Serving, use the Vary HTTP header to signal your changes depending on the user-agent. If you are using separate URLs, signal the relationship between two URLs by tag with rel="canonical" and rel="alternate" elements.
Having large groups of content that all revolve around the same topic will build more relevance around keywords that you're trying to rank for within these topics, and it makes it much easier for Google to associate your content with specific topics. Not only that, but it makes it much easier to interlink between your content, pushing more internal links through your website.
Because the act of linking to a site does not imply ownership or endorsement, you do not need to ask permission to link to a site that is publicly accessible. For example, if you found a site's URL through a search engine, then linking to it shouldn't have legal ramifications. There have been one or two cases in the U.S. that implied that the act of linking without permission is legally actionable, but these have been overturned every time.
Google’s local search results are displayed within Google Maps after a user searches for a keyword that includes a location, such as “pizza New York.” Landing within Google’s local search results requires that you have a Google My Business account. This is key for brick-and-mortar-based businesses because it puts your business in front of local people ready to buy.
