So I have been able to successfully create traffic for my web site: The Ultimate Green List, using Pay-per click advertising and blog exchanges.
Of course I would not be able to afford it if my clicks were anywhere from 50 cents to one dollar per click. After finding the proper keywords, I was able to bring the cost down to 5 cents per click. Now that is not bad.
Of course I did that using Google's Adwords. Using Yahoo's tool is a little more tricky, but I am on my way there to lowering its cost also. It is taking me a little longer due to the way that Yahoo does not allow matches and also does not distinguish between singular and plural of keywords. You have to be more creative with Yahoo to get your number of keywords up. But that is another post.
My top 6 things to remember when you are starting a PPC campaign:
Think about what you are advertising and what you want you customers to see. The ads and the landing pages should match your text ads and keywords. If your text ads do not match to or relate to your landing page Google can and will disapprove the ad.
Do not bid more than you are willing to lose. If you can only afford $300 per month you can only budget $10 per day. Also, do not use Google's recommendation, because you will run out of money fast.
Get your keyword tools ready and find as many keywords as you can think of related to the information on your landing page. Don't stop until you have a minimum of 150 keywords. There is no maximum number.( as long as you keep within the related parameters) Remember to use the "keyword" and [keyword] for every keyword you find. This trick triples your base number of keywords.
Test different ads. Ads are never optimized until you have an optimum CTR (click through rate). What is that magic number? 1% on the low end. Anything higher than 1 % is a job well done.
Follow up on your campaigns daily...if not twice to three times daily. This is to make sure that you are getting impressions and ultimately clicks and sales. This also insures that you are staying within your budget. Or if you are below your budget, you may adjust it up to get more exposure and therefore more clicks.
Last but not least educate yourself. There are many Gurus out there. I don't claim to be an expert. I have educated myself on pay-per-click and used it successfully to get targeted traffic to my sites.
I hope this gets you off on a good start with your advertising campaign.
Good luck and bid carefully.
