Thanks + question

[landed1]

Hi
Thank you for this resource. I found this as site ground staff recommending this as a resource.
I have a wordpress site and have a question on any side effects of having these lines -

Options All -Indexes
RewriteEngine on

I already have the later in a block so have removed it. The other I am not sure about or if I need it. I am also using this in a parent folder for a few sub sites to all share the same bad crawl traffic.

Thanks
