If you are interested in your website ranking well in the search results of Google and Co., then you should already think about some points during the project planning. This starts with a keyword analysis: For which search terms (or short phrases) should the website be optimized so that it is listed on the first results pages when these search terms are entered? You should not answer this question out of the blue, because a correct keyword selection requires first of all a keyword analysis. It is of little use to optimize your website for a keyword that is either searched for by "everyone" (in which case the competition is fierce) or is so exotic that hardly anyone searches for it (in which case the search volume is too low). To achieve an optimum here, there are various (here free) analysis tools on the net:

The selected keywords should be used organically in the texts of the web pages without keyword stuffing. In other words, the text should not be overloaded with the keyword selected for the page, because the search engine crawlers do not like that. It is better to place keywords in image tags and image descriptions. You should also try using synonyms and related words. Using your main keyword as part of the URL is also a thoroughly good idea and helps to improve the ranking.
Tip: Analyze the websites of your main competitors in terms of keyword usage or optimization and think about what you can do better.
The be-all and end-all of SEO, however, is that you must first and foremost deliver high-quality content, regardless of other measures, in order to rank highly. Search engines now focus on the benefits that a website offers its visitors. If you keep the visitor and his guidance (navigation) through your website in mind, Google will honor this accordingly in its search results.
Furthermore, you should pay attention to a logical structure of your website, which you can achieve independently of the actual content by a flawless hierarchical structure of the headings used. Thus, a web page should always have only one h0 heading and all other headings should be used in the correct hierarchical level and without omitting hierarchical levels. For example, use the Chrome extension "SEO META in 1 Click" to detect any errors in this regard.
For fast loading times (also an important SEO factor!) and for responsive design, Builderall and "Cheetah" (almost) take care of themselves. "Almost" means that, of course, there is still some work left for you as a web designer. Let's take the embedding of images. A good rule is to optimize the size of pixel graphics before integrating them into a web page. This means that, if possible, use an external tool (such as IrfanView) to resize the relevant images to the length and width that they will be displayed on the web page. It's simply a waste of resources if you leave an image at a resolution of, say 3840x2160 pixels, only to have it automatically resized to 640x480 pixels on the website afterwards. It can also make sense to use a compression service to resize jpeg files to a size that allows them to load particularly quickly over the web.

Furthermore, you should take care to avoid duplicate content on your website. As a rule, search engines don't like to see this and it worsens the ranking. By the way, a very good tool to detect duplicate content is "Siteliner":
