You're an SEO. You are tweaking client pages and billing your clients at the end of the month. Is there a standard industry practice of what you should actually put on your client bills, such as work completed?
There is no "industry practice" from what many of us have heard. However, in the event of any work completed, this is something you need to judge for yourself. If it's a small invoiced amount, typically, you don't need to do a breakdown of work completed. If it's a lot larger, however, you may want to tell your client exactly what work was performed.
Torka makes a good statement regarding acceptable billing practices that work for you and the client. Your results may vary:
I think the goal should be to achieve balance so the client feels comfortable they're getting what they pay for, and you aren't overly burdened with recordkeeping and reporting requirements.
If in doubt, discuss with your client.
