So I have several different point of sale hardware bundles on my website and using <h4> tags I wrote out what type it is and i wrote "POS (point of sale)" on all of them, would that be an issue?
No it will not crease any issues for your website...
What kind of issue do you think it can cause? Please specify you thoughts so I may be able to help with the answer. Cheers
Is the issue you are worried about is keyword stuffing? It would be pretty apparent to Google if you were targeting "POS" as your keyword. If not it really shouldn't be a big deal.
i think it's ok. it will not cause any problems and will not effect on the website or it's ranking in google.
