is it ok to submit a UK Website to Non UK based

Yes, it's fine.

directories for link building purposes or would search engines see this as
back link scamming

Just submit to some quality directories. (Most of inner pages are cached with Google)
Don't submit too much a day, Submission 10-30/day is OK.

Thats totally fine u can and as mr. hotpop said do the quality work..

Yes its ok, just concentrate on quality links in stead of quantity, if you have quality links then you can go far ahead in this game.

Good question as i had recently started submitting to directories and wondered the same thing. glad its ok to do it to non uk ones aswell.

your question is very nice i recently join submitting the directories and contact writing it is interesting and very cool.

This is correct advice. Submitting to NonUk directories is fine. And limit your submissions to a few a day.

Also, Try to submit to niche directories if you can find them. I think they will give more traffic than generic directories.

Both are important what are you posting and where are you posting. If you posting unique or quality content on niche site then definitely you will get result.
