how to advetis locksmith bisnus?

I don’t know about 411. Talk to either the city, county or state government about that.

Look in your Yellow Pages under Locksmith and see what competitors advertising looks like. Choose a name that will put you near first in the list. Buy a bigger ad in the book than the competitors.

If you have a store front, invest in a sign that attracts people.

The million $ question… here is my 1G answer for free:
1. Location Location Location
2. Advertise using fliers
3. Magnet cards (even though those are not always helpful for lockout)
4. I personally use the services of a company that provides me leads to my business try and contact them at bambinomail@gmail.com. VERY RECOMMENDED !!! the guys name is Edi, I think.
5. Yellow pages- even though according to my experience they are a bit expensive in compare to what you get.
6. Get an easy to remember Tel. number

Thats it for today,
Good luck
