Also keep these things in mind:
1) Sitemap must be less than 10 MB (10,485,760 bytes) and can contain maximum 50,000 urls. if you have more uls than this create multiple sitemap files and use a sitemap index file.
2) Put your sitemap in website root directory and add the url of your sitemap in robots.txt.
3) sitemap.xml can be compressed using grip for faster loading.
Broken link: a broken link is an inaccessible link or url of a website. a higher rate of broken links have a negative effect on search engine ranking due to reduced link equity. it also has a bad impact on user experience. There are several reasons for broken link. All are listed below.
1) An incorrect link entered by you.
2) The destination website removed the linked web page given by you. (A common 404 error).
3) The destination website is irreversibly moved or not exists anymore. (Changing domain or site blocked or dysfunctional).
4) User may behind some firewall or alike software or security mechanism that is blocking the access to the destination website.
5) You have provided a link to a site that is blocked by firewall or alike software for outside access.

Older HTML tags and attributes that have been superseded by other more functional or flexible alternatives (whether as HTML or as CSS ) are declared as deprecated in HTML4 by the W3C - the consortium that sets the HTML standards. Browsers should continue to support deprecated tags and attributes, but eventually these tags are likely to become obsolete and so future support cannot be guaranteed.

GZIP Compression
GZIP compression is disabled.
Knowledge Base
Knowledge Base
GZIP is a generic compressor that can be applied to any stream of bytes: under the hood it remembers some of the previously seen content and attempts to find and replace duplicate data fragments in an efficient way - for the curious, great low-level explanation of GZIP. However, in practice, GZIP performs best on text-based content, often achieving compression rates of as high as 70-90% for larger files, whereas running GZIP on assets that are already compressed via alternative algorithms (e.g. most image formats) yields little to no improvement. It is also recommended that, GZIP compressed size should be <=33 KB

Both refer to the link mywebsite.com/home. So all the different url with same content or page now comes under the link or url mywebsite.com/home. Which will boost up your search engine ranking by eliminating content duplication. Use canonical tag for all the same urls.

Audit Data
Keep request counts low and transfer sizes small
51 requests • 3,147 KiB
To set budgets for the quantity and size of page resources, add a budget.json file. Learn More
Eliminate render-blocking resources
Potential savings of 750 ms
Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles. Learn More
Efficiently encode images
Optimized images load faster and consume less cellular data. Learn More
Enable text compression
Text-based resources should be served with compression (gzip, deflate or brotli) to minimize total network bytes. Learn More
Serve static assets with an efficient cache policy
11 resources found
A long cache lifetime can speed up repeat visits to your page. Learn More
Reduce the impact of third-party code
Third-party code blocked the main thread for 2,390 ms
Third-party code can significantly impact load performance. Limit the number of redundant third-party providers and try to load third-party code after your page has primarily finished loading. Learn More
First Contentful Paint (3G)
3060 ms
First Contentful Paint 3G marks the time at which the first text or image is painted while on a 3G network. Learn More
Total Blocking Time
1,680 ms
Sum of all time periods between FCP and Time to Interactive, when task length exceeded 50ms, expressed in milliseconds.
Reduce JavaScript execution time
5.3 s
Consider reducing the time spent parsing, compiling, and executing JS. You may find delivering smaller JS payloads helps with this. Learn More
Defer offscreen images
Potential savings of 827 KiB
Consider lazy-loading offscreen and hidden images after all critical resources have finished loading to lower time to interactive. Learn More
Server Backend Latencies
0 ms
Server latencies can impact web performance. If the server latency of an origin is high, it's an indication the server is overloaded or has poor backend performance. Learn More
Properly size images
Potential savings of 908 KiB
Serve images that are appropriately-sized to save cellular data and improve load time. Learn More
Reduce unused CSS
Potential savings of 70 KiB
Reduce unused rules from stylesheets and defer CSS not used for above-the-fold content to decrease bytes consumed by network activity. Learn More
Avoid enormous network payloads
Total size was 3,147 KiB
Large network payloads cost users real money and are highly correlated with long load times. Learn More
Minimize main-thread work
6.8 s
Consider reducing the time spent parsing, compiling and executing JS. You may find delivering smaller JS payloads helps with this. Learn More
Avoid chaining critical requests
4 chains found
The Critical Request Chains below show you what resources are loaded with a high priority. Consider reducing the length of chains, reducing the download size of resources, or deferring the download of unnecessary resources to improve page load. Learn More
Avoids an excessive DOM size
418 elements
A large DOM will increase memory usage, cause longer Learn More
Avoid multiple page redirects
Redirects introduce additional delays before the page can be loaded. Learn More
Minify JavaScript
Minifying JavaScript files can reduce payload sizes and script parse time. Learn More
User Timing marks and measures
10 user timings
Consider instrumenting your app with the User Timing API to measure your app's real-world performance during key user experiences. Learn More
Network Round Trip Times
0 ms
Network round trip times (RTT) have a large impact on performance. If the RTT to an origin is high, it's an indication that servers closer to the user could improve performance. Learn More
