The Secret Sauce
I get that companies that focus on search engine optimization want to pick up customers. Just like politics, there is a lot of mud slinging happening between all the competitors. Each one of these companies, or at least more often than not, claims to know the "secret ingredient" to get your page to rank.
Its like this. If we cannot even figure out what makes Coca-cola so damn delicious, what gives us the ability to pick apart technology companies like Google, Bing, and Yahoo and the manner they rank their search results? If we cannot figure out the secret ingredient in a soda, we sure the hell won't be able to discover the secret ingredient of SEO.
The Magic Wand...
First, though the internet is amazing, IT IS NOT HOGWARTS! You cannot just wave a magic wand (or at least not quite yet) and pull that iPad right out of the computer screen when you are online visiting the Amazon or other similar sites. The internet still takes a degree of work and part of this work for any SEO company is getting their page to be visible for users. To do this, they need to at least be on the first page of the search engines, but preferably within one of the top three results.
A lot of search engine optimization companies do not like to do the work that their clients need. Instead, many of them take short cuts and use black hat SEO on their clients websites and get its rank knocked down to where nobody will find it. NEVER HIRE AN SEO COMPANY THAT USES BLACK HAT TECHNIQUES!!!
SEO Golden Gun and Silver Bullet
To be quite blunt here, any company that leads you into thinking they have the SEO golden gun and can get you to rank almost immediately is blowing smoke up your ass. There really is no other way to say it. I challenge one search engine optimization company that makes any claim like this to prove it, using only white hat techniques. If you can show me a company that has the silver bullet to beat Google's Algorithm, I will move to North Korea and not leave until I have a photograph of Kim Jung Un on a Unicorn.
You ever hear the saying, " You can't BS a BSer? "?
Sadly, telling clients lies or half truths is the route that most SEO companies take. I would even go as far to say that even North Korea bolsters more truth than some search engine optimization companies. When it is all said and done, there is no SEO secret formula. Yes, there are some things that many SEO experts agree on, but a secret formula for SEO is still more reclusive than North Korea.
