Keyword update

Hello,

Thank you for contacting Rank Math, and sorry for any inconvenience caused.

It seems like the memory is getting exhausted. Please contact your web host and ask them to increase the memory.

Or, you can try to limit the number of posts and see if that helps.

You can limit the number of posts that you process each time by setting a limit on the posts like so:

'posts_per_page' => 100

You can then add an offset to the function as well to continue adding the focus keywords to newer posts. So, after changing the first 100 posts you add an offset of 100 to the function like so:

'offset' => 100

You can continue to increase the offset by 100 until it runs through all of the posts.

Each time you run the function, you can add 100 to the offset value like,

1st time : 'offset' => 0, 
2nd time : 'offset' => 100,
3rd time : 'offset' => 200,

And so on...

Hope this helps solve your issues.

Looking forward to helping you.
