Here are the key takeaways from this infographic.
Problems concerning links and/or redirects can be thorny. Some of these problems can severely hurt your website on a fundamental level. Others shouldn’t even be seen as mistakes. With a surprising number of websites still suffering from things like redirect chains and loops, make sure every main page associated with your site works properly.
2) Broken Internal Links
Try to avoid 4xx errors and 5xx errors whenever possible.
Most website owners understand that the sitemap should be seen as the heart and soul of your website. A good sitemap is going to ensure a search bot will stay on the correct path, without missing anything important with your website.
4) Robots.txt And URL Structure
Make sure to avoid any error in your robots.txt files. Many errors can lead to problems with proper indexing. Even an error in a disallowed page can cause confusion with the search bots crawling over your website. Furthermore, you will also want to keep your URL structure in mind. Your URL structure should not only be clear, but it should adhere to a proper length. These things should be optimized for not only your visitors, but for any search bots that are going to crawl across your site. Focusing on simple, SEO-friendly structures is the right way to go.
5) On-page Optimizations
Avoid duplicate content, a low text-to-HTML ratio, and a low word count on your page. A duplicate meta-description can also hurt your on-page optimization potential. Missing meta-descriptions are even worse, and this continues to be a major problem amongst even the biggest websites and businesses. It is also smart to keep in mind the value of title tag to the CTR of your website. It can also be useful to remember your H1 tags, which can give your users an indication of what a specific webpage might be about.
While images do not directly impact your rankings, it is still something that you are going to want to keep in mind. After all, you want your users to have the best experience possible.
7) Technical SEO
You won’t want to forget about the technical SEO side of things either. Page speed is certainly something you need to pay attention to. If it isn’t fast enough, people are going to go somewhere else. You also want to avoid old technology. Finally, in this day and age, every website needs to be optimized for the mobile experience.
