A few links down and I've noticed that Brian has a link from WordPress.org. Not bad! Turns out that his content has been referenced within one of WordPress's codex posts. If I were to reach out and offer some additional insight, citing one of my articles, there's a chance I could bag a similar link, especially considering they have a 'Useful Resources' section.
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.
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]

Hi Brian, a very useful post, thanks for sharing. These things turned to be very useful for us: blocking thin content/pages from Google index, adjusting meta titles/descriptions and content of popular articles, improving internal links, improving page speed, implementing schema (didn’t notice a big difference here), optimizing images and their alt tags, making sure the site is mobile friendly and there are no accessibility issues (Lighthouse in Google Chrome helped a lot), some link building activity (long term) and of course keyword research and mapping. Thanks again for providing valuable info, regards.
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.
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.
Next, log into Google AdWords and click “Tools” > “Keyword Planner.” Once you’re on the Keyword Planner menu, click “Search for new keywords using a phrase, website or category.” Complete the form that appears; to start with, search for your type of business and location. For example, if you own a hair salon in Chicago, you would want to enter “hair salon Chicago.”
