Are query strings bad for SEO?

Multiple query string parameters can be used within a single URL, which can impact a website's SEO and organic search performance in several ways, including causing duplicate content and crawling issues.

Can a query string be too long?

Although officially there is no limit specified by RFC 2616, many security protocols and recommendations state that maxQueryStrings on a server should be set to a maximum character limit of 1024. While the entire URL, including the querystring, should be set to a max of 2048 characters.

Is it safe to pass parameters in URL?

The reality is that URLS and query parameters aren't secure. They should never contain sensitive or important information (passwords, static shared secrets, private information, etc). It is asking for trouble, especially when browser spyware gets involved.

Should I remove query strings?

Plus, query strings prevent servers from caching your website. As a result, your page speed slows down. By removing the query string, you improve caching and decrease the page load time.
