* Hi there and thank you for your awesome Plugin!
* I recently noticed Google Search Results for my page pointing to `https://my-
domain.com/?`, and I’m wondering where the ? is coming from. I believe, it could
be a caching issue:
* I tried the following:
– Purging the Cache and preloading. – I then visited `
https://my-domain.com/?`, and the cached version of `https://my-domain.com/`
got updated.
* Is that supposed to happen?
* I’m using TranslatePress, which dynamically changes hreflang urls. So all subsequent
visitors receive a (cached) homepage where the hreflang urls look like this: `
https://my-domain.com/{lang_id}/?`.
* I’ve no idea how to get rid of this ?. Any help would be greatly appreciated!

* The ? is a query string. After the question mark you can pass key-value pairs
and use them server-side.
* Here is a guide that you should find helpful;

* Thank you for your reply! I had a look at the link but it doesn’t solve my issue.
* My question is getting more clear by replicating these steps:
* 1.) Open a random page which is currently cached by WP-Optimize.
2.) Look at
the Source Code and find the comment at the bottom: 3.) Manually add a /? to the url in the address bar and
press enter. 4.) Go back (remove the ? again), refresh and have a look at the
last modified Date in the comment again. You will see, that the Date has changed.
* Why would that happen? Am I missing something? WP-Optimize doesn’t cache urls
with Query Strings. Why does a single question mark cause the cache to be modified,
when a full Query String like ?a=b does not?
I may be totally wrong, but I think
this behaviour might be the root cause for my little url problem mentioned above.
* Again, thanks for taking your time!

* @boardingfk Yes, I can confirm that this is a bug and will be solved in our next
release. However, I’m wondering how a URL with `?` is ended up in google search
results

* Sounds great, thanks!
* So my theorie goes like this:
1.) Someone visited our homepage with an `/?`
at the end of the url. 2.) Translatepress plugin looks at the url and changes
the href attributes in the link-Elements accordingly:
* ```
```
* 3.) The html file is then cached by WP-Optimize and served to all subsequent
visitors of our homepage, including GoogleBot.
4.) Google uses the urls from
the link-Elements in the search results.
* Hope the next update of WP-Optimize will prove me right! 😉
