Performance can be enhanced with the compression of images, the elimination of unused resources, utilization of caching and optimized server response time.
2. Mobile Optimization

Great mobile experience is achieved by these: responsive design, readable text, easy to navigate and appropriately sized buttons.
3. Crawlability and Indexability
Crawlability is how well search engine bots can reach the pages of a website. Indexability is the term that is used to describe whether the pages can "be processed and added to a search engine's index".
Several things inside the website can impact how the website is crawled and indexed, including the internal linking structure, structure, `robots.txt`, and meta robots directives.
4. XML Sitemap

You may not have a sitemap but this can assist search engines find the important pages.
5. Robots.txt
A robots.txt file is a web page that instructs search engine bots on which parts of your page(s) to crawl.
It will need to be installed with extreme care. Confusing pages you would not want to be confused by accidentally blocking important pages can mean that the search engine can't reach the pages with the content you want into the search results.
6. Canonical Tags
The same/or identical content can be available in different urls. To strip some of the query parameters off and mainly represent the element that matters, it is used in long URLs containing many different query parameters.If you have a long URL (with a lot of query parameters), and you want, say, a search engine to present a different version of that URL instead, they can be very helpful.
This is highly advantageous in the event you have a variety of URLs or a variety of webpage parameters.
7. Redirects and Broken Links.
Websites are a dynamic environment. Pages may be deleted, renamed and moved to a new URL. Use the appropriate redirects to make the user and search engine take them to the correct new page linked with the old page, e.g. by using the 301 redirect.
Ensure that checks on broken links and unnecessary redirects are conducted from time to time so that the structure of the website is kept clean.
8. HTTPS and Security
HTTPS is one of the methods that a website can use to connect with their visitors securely. Ensures data security when sending and receiving, allows for secure browsing by the user.
