Stay away it might go off.

I have learned a lot about SEO (search engine optimization) in the last few months. I have learned enough to tell me that it is better left up to experts, and experts with integrity at that.
As a business with a web site we want to direct traffic to (www.marsworkwear.com) of course we want our site address to pull up on the front page every time some one searches for a product or service that we sell. (shoe covers, coveralls,floor protection and safety supplies)
That being so, it is easy to try to take short cuts on the way to the top. These short cuts are really just cheating and are frowned upon by such search engines as google. These so called black hat techniques can be very effective in getting your web site rated at the top. However, they can also get you slapped down very hard if you get caught doing it.
I have always thought that the stress of always wondering if your going to get caught is not worth the risk of doing something improper. In other words I don't do the crime cause I don't want to do the time. Some people may take the low road and believe that the end always justifies the means as long as they make money for themselves or their company. This may be a profitable way to do business, but it ends up putting you in a bad light.
I firmly believe the anecdote about arrows. "what is fired straight up comes straight down, but what is fired at a gradual ascent stays up for a long time"
Don't trust to luck that you won't get caught. Obey the rules, play the game the right way and when you succeed there is great satisfaction in knowing that you were able to do it with integrity.
We are moving up slowly but surely.(almost 100 places in the last 2 months) The person we hired is doing a great job, and doing it the right way. My advice to all out there is get a experts advice or even pay for a service, but always check their integrity and remember, If it's too good too be true it's too good too be true.
