Keep a consistent flow of relevant content - While meta tags and titles are important to SEO, they are not the only contributing factor to Google rankings. When Google returns results for a search, it seeks to find the most useful information for the query. Adding content such as blog posts, articles, pictures and videos not only gives you another forum for keyword-rich copy, it also serves your customer by providing unique information and education about what you offer.
Attempting to replace a dead link with your own is easily and routinely identified as spam by the Wikipedia community, which expects dead links to be replaced to equivalent links at Persistent attempts will quickly get your account blocked, and your webiste can be blacklisted (the Wikipedia blacklist is public, and there is evidence that Google uses it to determine rankings), which will have negative SEO consequences.

SEO is also about making your search engine result relevant to the user's search query so more people click the result when it is shown in search. In this process, snippets of text and meta data are optimized to ensure your snippet of information is appealing in the context of the search query to obtain a high CTR (click through rate) from search results.

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.

Thank you so much for these great SEO techniques you posted on your blog. I also follow you on your youtube and listened to almost all of your videos and sometimes I re-listen just to refresh my mind. Because of your techniques, we managed to bring our website to the first pages within a month. Adding external links was something I never imagined that it would work. But it seems like it is working. Anyway, please accept my personal thank you for coming up with and sharing these techniques. I look forward to your new blog posts and youtube videos!
WOW. I consider myself a total newbie to SEO, but I’ve been working on my Squarespace site for my small business for about 3 years and have read dozens of articles on how to improve SEO. So far, this has been the MOST USEFUL and information-packed resource I’ve found so far. I’m honestly shocked that this is free to access. I haven’t even completely consumed this content yet (I’ve bookmarked it to come back to!) but I’ve already made some significant changes to my SEO strategy, including adding a couple of infographics to blog posts, changing my internal and external linking habits, editing meta descriptions, and a bunch more. Thanks for all the time and passion you’ve out into this.
