1. Make sure your website is mobile friendly
Having a mobile-friendly site in 2023 is the most basic technical SEO trick.
One of Google’s major algorithm updates in 2015 was to give increased preference to mobile-friendly and responsive websites. In what has been called ” Mobilegeddon “. Several prominent websites have been penalized for not adopting a more mobile-friendly web template.
Google also announced 2 years ago that the indexing of sites will be based on mobile-first (Mobile-First indexing).
So today, having a mobile-friendly website is more important than ever. This is really the basis of technical SEO in 2023.
Several free tools are available on the web to check the mobile-friendliness of your website, for example:
- Google Mobile Optimization Test
- Bing Mobile Usability Testing Tool
Google’s Mobile Friendly test will determine if your website meets Google’s criteria for a mobile-optimized website .
It is very easy to use. You only have to insert the url of your site or the page of your choice.
Google (and the majority of other tools) gives you the result concerning the test and also gives you some advice to correct the problem of your site if necessary.
2. Create and Optimize your XML sitemap
Sitemaps are necessary for Google to find and index your web pages.
Although your site can be indexed by Google without sending a sitemap, it helps to speed up the indexing frequency of your website and at the same time it shows search engines the whole structure and URLs of your site.
Fortunately, it’s easy to create an XML sitemap. If you are a WordPress user, you can generate it using free WordPress plugins like Yoast or Google XML Sitemaps. Otherwise, there are several websites online that allow you to generate your sitemap for free.
Once you’ve created the sitemap, submit it to Google through the Google Search Console.
To do this, log into your Google Search Console account and navigate to Sitemaps -> Add New Sitemap , then press “Submit”.
Once your sitemap is successfully submitted, follow XML sitemap best practices:
- Make sure your pages are not blocked by the robots.txt file (this has nothing to do with your XML sitemap)
- Prioritize high-quality pages in your sitemap
- If you have a large site with over 50,000 URLs, use dynamic XML sitemaps. For example, you can send your site’s rss feed as a sitemap.
3. Speed up your website loading speed
Site speed matters a lot to search engines. Don’t make the mistake. If your site is slow and takes a long time to respond, Google will apply a small penalty to your website. It is an evaluation criterion among the most important Google ranking factors .
This means that even if your content is great, your website will rank lower in the SERPs unlike if your website had a faster loading time.
This is a technical SEO aspect that you simply cannot ignore.
You can use one of the following free tools to test your site’s speed:

According to Yahoo, enabling compression on your website can shrink HTML and CSS files by 50-70% and dramatically increase site speed.

An internal link is a hypertext link that points to another page on the same website.

Google cannot see the content of an image. Instead, it uses metadata such as image file name and image alt text (ALT) to determine the content of an image.
7. Use Canonical URLs to Avoid Duplicate Content Issues
