I see it all the time, where people sell a product and put the most ridiculous keywords and are impressed when their CTR hits 0.10%.
Let me give you an example...
If you sell Indonesian Beds, then the term 'Beds' is a BAD keyword for you! The best keywords will be:
- Indonesian Beds
- Indonesian Furniture
- Teak Bed
It sounds simple, but people completely over looks this. By having 'Beds' on broad match, you are opening your ads to appear to anyone search for anything to do with beds such as:
- Camping beds
- Cheap beds
- Argos beds
- Beds for sale
- King size double beds
- Love beds
You get the idea!
Reply to this post with your site and I will be happy to suggest a few terms that you should be targeting.
Take care!
