In order to optimize your site, you need to make sure you are including the keywords that you want to rank for multiple times throughout your site. Also, ensure your site has complete and up-to-date contact information, that you’re using appropriate meta tags, and that you include pertinent business information as text—not text on images that Google can’t search.
All sites have a home or "root" page, which is usually the most frequented page on the site and the starting place of navigation for many visitors. Unless your site has only a handful of pages, you should think about how visitors will go from a general page (your root page) to a page containing more specific content. Do you have enough pages around a specific topic area that it would make sense to create a page describing these related pages (for example, root page -> related topic listing -> specific topic)? Do you have hundreds of different products that need to be classified under multiple category and subcategory pages?
One of my best pieces of advice when it comes to SEO for small businesses is to truly spend some time understanding your audience and their intent. Even if your website is perfectly optimized, if it’s done for the wrong audience, you will not see good traffic. Google is taking audience intent into account more and more, as updates like RankBrain try to understand the semantics of a search query and not just the literal definition of the words. If you can comprehensively answer the questions your audience is asking, your site will rank highly in Google organically.
If you’re updating the whole post, I think bloggers should create a brand new post and link the old to the new. I know, you’re starting over with no “link juice,” but at least it’s clear to the reader that the post has gotten a makeover. I remember reading a new post of yours a few months. I was about 25% through it and thought “man this sounds familiar.” So I checked it out on archive.org and realized that you had updated and republished it.
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.
The W3C Recommendation called XLink describes hyperlinks that offer a far greater degree of functionality than those offered in HTML. These extended links can be multidirectional, linking from, within, and between XML documents. It can also describe simple links, which are unidirectional and therefore offer no more functionality than hyperlinks in HTML.
One of my favorite ways to give content a boost is to run ads on Facebook targeting people with interests that are relevant to the content. It’s fairly low cost since you are offering a free piece of content. By targeting people with relevant interests to your content, you drive the right people to the content and into the top of your funnel. And if your content resonates with them, they’ll share, link, and engage with the content in ways that will help Google see its value.
Organic results includes a wider range of websites—not just local businesses. While location may still be a factor in the organic results, it is not generally the dominant factor. The main factor is the authority of the website (or the credibility of the site), external links back to the site, the length of time the site has been live, and other considerations. This is why you will often see sites such as Yelp, Angie’s List, and Facebook show up high in search results.
