The drawbacks of using Flash on a website
Drawbacks of Flash for SEO and more
- High load on the processor, which leads to the fast discharge of a laptop or smartphone;
- uncontrolled errors, as a result of which applications and even browsers stop working;
- issues with launching applications;
- the right mouse button does not work in Flash versions prior to 11.2;
- simplified malware access;
- poor content indexing;
- the inability to convert vector images to other formats (.cdr or .ai).

Adobe has predicted the likely death of Flash in the coming years. In summer 2017, the developers announced that the technology support would stop at the end of 2020.
Microsoft also announced they would stop using this plugin. Starting from 2019 it will be gradually pulled out from popular browsers and will no longer be used in them by default. The full stop of Flash Player in Windows is planned for the year 2020.
At the end of 2016, Google Chrome stopped supporting the plugin. Internet Explorer and Edge will do the same in 2019, and Mozilla will stop updating the plugin in 2020.
Flash vulnerability to malware on a website
This is becoming less frequent due to the fact that content developers are abandoning outdated technology. The graph shows how the number of websites with Flash has declined since the beginning of the 2010s, while the JavaScript plugin has become more popular.

Negative Factors of Flash for SEO
- Non-indexable content. This is the most important factor: search engines simply won't understand what is on the page if it has only Flash-animation;
- increased page load time;
- risk of infection of the entire website via Flash, the deterioration of ranking positions because the viruses get on the pages;
- imperception by mobile devices – high bounce rate.
Conclusion
The main reasons why the plugin fails were security holes, excessive consumption of processor resources and regular operation errors.
All popular mobile platforms and browsers disable Flash plugin support, and it will be completely wiped off by the end of 2020.
