Re: what's the best way to advertise on google? - interior design?
Hi Evelyn and welcome to the forum. If I may be a little cheeky that's a bit like me asking you "What's the best way to decorate my house?". It's a big question and there are no simple, easy answers - certainly without knowing a lot more about your business and your objectives, but I'll give you some food for thought.
1. Most important of all is to have an objective. This may seem obvious but to those of us who have been doing this a while it's surprisingly common to find companies that are running advertising campaigns (all sorts, not just Adwords) without any clear objective or target. It usually falls down to roughly two areas: brand awareness or promotional (sales).
2. Make sure you're ready to advertise. Assuming you're going to be pointing people at a website, make sure that website is as good as it can possibly be at promoting your brand or your service. Again, you'd be amazed (or horrified) at how much money people spend on advertising that sends visitors to a terrible website they can't use or navigate.
3. Start slow and careful. Start with a very small budget, maybe no more than $50 in total, and experiment with that. Don't try to do everything in one hit straight away. Try using just a handful of really tightly focused Keywords on one aspect of your business then build from there.
Come back and tell us some more about your business and we'll give you some more specific feedback.
