In a series of books and articles published from 1964 through 1980, Nelson transposed Bush's concept of automated cross-referencing into the computer context, made it applicable to specific text strings rather than whole pages, generalized it from a local desk-sized machine to a theoretical proprietary worldwide computer network, and advocated the creation of such a network. Though Nelson's Xanadu Corporation was eventually funded by Autodesk in the 1980s, it never created this proprietary public-access network. Meanwhile, working independently, a team led by Douglas Engelbart (with Jeff Rulifson as chief programmer) was the first to implement the hyperlink concept for scrolling within a single document (1966), and soon after for connecting between paragraphs within separate documents (1968), with NLS. Ben Shneiderman working with graduate student Dan Ostroff designed and implemented the highlighted link in the HyperTIES system in 1983. HyperTIES was used to produce the world's first electronic journal, the July 1988 Communications of ACM, which was cited as the source for the link concept in Tim Berners-Lee's Spring 1989 manifesto for the Web. In 1988, Ben Shneiderman and Greg Kearsley used HyperTIES to publish "Hypertext Hands-On!", the world's first electronic book.[citation needed]
As keywords are essentially the backbone of on-page SEO, you need to pay a lot of attention to them. There is no reason not to include them in your URLs.  The inclusion has its benefits. When you assimilate the targeted keyword into the URL, you are ensuring that Google’s has another reason and way to consider your article as more relevant for a particular phrase.

When your business is listed in an online directory, it is known as a structured citation. These citations increase exposure and website domain authority while associating your business name with existing high-authority sites like Yelp—all of which is favorable to Google. To create an effective structured citation, include full business contact information on your directories and be consistent with formatting.

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.
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.
