Thanks for sharing these tips, Brian. Agree with all of these, except maybe #3 Delete zombie pages. A better strategy would be to update these pages with fresh content and convert them into a long form blog posts/guides. Deleting them entirely would mean either setting up a 404 or 301 redirect – both of which can hurt your organic traffic in the short run.
When someone searches for the name of your business specifically, Google will pull information from your Google My Business page and display it in a panel on the right-hand side of the search results, increasing your business’ exposure. This is great for small businesses, because not only do you get a lot of space on the first page of Google’s organic search results, but you are also able to immediately show what your business is about. Again, the panel is only available to those who have set up their free Google My Business page.
The effect of following a hyperlink may vary with the hypertext system and may sometimes depend on the link itself; for instance, on the World Wide Web most hyperlinks cause the target document to replace the document being displayed, but some are marked to cause the target document to open in a new window (or, perhaps, in a new tab[2]). Another possibility is transclusion, for which the link target is a document fragment that replaces the link anchor within the source document. Not only persons browsing the document follow hyperlinks. These hyperlinks may also be followed automatically by programs. A program that traverses the hypertext, following each hyperlink and gathering all the retrieved documents is known as a Web spider or crawler.
Another reason is that if you're using an image as a link, the alt text for that image will be treated similarly to the anchor text of a text link. However, we don't recommend using too many images for links in your site's navigation when text links could serve the same purpose. Lastly, optimizing your image filenames and alt text makes it easier for image search projects like Google Image Search to better understand your images.
You can confer some of your site's reputation to another site when your site links to it. Sometimes users can take advantage of this by adding links to their own site in your comment sections or message boards. Or sometimes you might mention a site in a negative way and don't want to confer any of your reputation upon it. For example, imagine that you're writing a blog post on the topic of comment spamming and you want to call out a site that recently comment spammed your blog. You want to warn others of the site, so you include the link to it in your content; however, you certainly don't want to give the site some of your reputation from your link. This would be a good time to use nofollow.

The scientific literature is a place where link persistence is crucial to the public knowledge. A 2013 study in BMC Bioinformatics analyzed 15,000 links in abstracts from Thomson Reuters’ Web of Science citation index, founding that the median lifespan of Web pages was 9.3 years, and just 62% were archived.[10] The median lifespan of a Web page constitutes high-degree variable, but its order of magnitude usually is of some months.[11]
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.

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.
Paid search results are those in the top and bottom of the results page, indicated by the small “ad” icon. These are placements that businesses pay for to show up when users search specific keywords. Google Ads can be a very effective way of utilizing ad spend for those who are new or struggling to compete against businesses that rank higher in organic search results. It’s also great for businesses targeting keywords with high revenue potential.
