If you do great work with your search engine optimization (SEO), it could mean a significant amount of revenue for your business. At the same time, however, it is also an ongoing initiative. Once you generate a steady stream of traffic from SEO, you need to constantly be maintaining and improving your SEO in order to keep those rankings you worked so hard for.
On another note, we recently went through this same process with an entire site redesign. The executive team demanded we cut out over 75% of the pages on our site because they were useless to the visitor. It's been 60 days since the launch of the new site and I've been able to still increase rankings, long-tail keywords, and even organic traffic. It took a little bit of a "cowboy" mentality to get some simple things done (like using 301's instead of blocking the old content with robots.txt!). I predicted we would lose a lot of our long tail keywords...but we haven't....yet!
I second Rand's comment! Congrats on moving from the corporate world to the independent consultant. This is my goal for the near future. I too have been testing the waters of independent consulting, but it doesn't quite pay the bills yet! Sometimes I feel like I should find a mentor who has been where I am now and is where I want to go. Perhaps i'll find a few in this community over time!
Think about the words that a user might search for to find a piece of your content. Users who know a lot about the topic might use different keywords in their search queries than someone who is new to the topic. For example, a long-time football fan might search for [fifa], an acronym for the Fédération Internationale de Football Association, while a new fan might use a more general query like [football playoffs]. Anticipating these differences in search behavior and accounting for them while writing your content (using a good mix of keyword phrases) could produce positive results. Google Ads provides a handy Keyword Planner34 that helps you discover new keyword variations and see the approximate search volume for each keyword. Also, Google Search Console provides you with the top search queries your site appears for and the ones that led the most users to your site in the Performance Report35.
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.
Every website should have a content strategy focused around your top keywords. When you create content such as blog posts, videos, whitepapers, research reports and webinars, it gives people something to link to. In addition, the content you create can rank by itself in the search engines. For example, if you write a blog post on “How to Pick an SEO Company,” there is a possibility it will rank for some of the keywords you use in the title and in the body post, especially if the post gets linked to from other websites or shared a lot on social media. It also helps if your website as a whole already has significant high-quality links.
