=====================================
The meta tag "generator" is a piece of metadata that was once commonly used in web development to identify the software or service used to create a webpage.
In the world of trucking, we have a term, payload. Payload brings in a return for carrying it, the rest is non-paying and therefore a fuel expense. Excess meta tags that aren't being used by anyone just add to the load time, eat clock cycles, disk space and transmission packets.
In summary, having too many meta tags that are not being used can be problematic. However, meta tags are only useful if searching, indexing or special use consumers use them. The "generator" meta tag is only useful for identifying the software or service used to create the page.
It could be a significant security risk. I remove it if it shows up on any sites I do.
In this regard, avoiding the use of the "generator" meta tag can be beneficial in preventing security risks.
While the "generator" meta tag is not particularly useful in modern web development, it can be useful for identifying software or services used to create pages for various purposes. As an example, gathering statistical analysis on generator usage can be informative.
If you're gathering statistical analysis on that, it would be useful.
This suggests that the "generator" meta tag can be useful for statistical purposes.
You might think what you have there is secure… today. If I were one to write exploits, I'd be spidering and indexing on this tag, then as soon as a new exploit is discovered, I'd target my exploits to sites known to be vulnerable.
In terms of security, the "generator" meta tag can potentially provide information that could be used to identify vulnerabilities in software or services.
The "generator" meta tag is no longer a necessary or particularly useful attribute in modern web development. Its use can potentially lead to security risks, while its removal can have benefits in terms of faster page loads and reduced bandwidth usage.
