SEO tightly and thoroughly entered the Internet business - this market is estimated at tens of billions of dollars a year. A thousand of firms and SEO specialists provide their facilities. But how can we recognize professionals from the pseudo experts?

The easiest, but not the most competent way is to assess the company’s or freelancer portfolio. But the number of customers and the “complexity” of key phrases is not always the most important parameter. I think you understand, that there may be a lot of customers, but you’ll not read about their satisfaction with the results of the work in the portfolio.

Therefore, I think the person who decided to order SEO services should analyze this question in order to be able to distinguish specialists from slackers. The main signs of bad specialists:

Use one and the same strategy and the same sites in links exchange for various customer. One time, I’ve heard somebody said: “A good SEO specialist must have its base for links exchange.”
On the one hand it is good, but the other is better to use different sites for the links exchange and purchase. But it’s not about placement of articles and links in social networks and sites.

I advise you to place your information on several domains. When ordering some services they recommend to leave the old site in the network and all further production movement make at a new domain, while the information is fully duplicated on the web.

Provide adding your site to multiple search engines. Ultimately, these experts will do nothing to optimize your site. After all, the site falls into the main search engines. A special enclosure in fact solves nothing, except the speed of site appearance became higher.

Offer to use 302 redirections. Some companies when moving the site from one domain to another, recomend to use 302 redirection. If you understand the essence of this redirection, it should be obvious to you – it’s wrong.

Focus on exchange and purchase of the links. It is good, but don’t have a hang-up!
Too much attention paid to the keywords and pages descriptions. There are also experts who believe it is essential for the optimization. This is certainly important parameters, but not the crucial.

Offer to create multiple satellite sites for individual keywords, that is not very good. It’s better to place all the information in one domain than dispel your attention on many sites, each of which requires an advance.

Tell you about the effectiveness of placing hidden text on the site.
Claim that they know the algorithm of Google and other search engines. I think many specialists who have worked with on the Google development, still don’t understand his work.
Because the architecture is very complicated and involves thousands of algorithms and parameters. And I do not think that such media leak is possible in the SEO firm.

Ensure the first place in the search extradition. No one can guarantee placement of the site in the first place for “value” keyword. You can guarantee low query from 3-4 words. Indeed, as popular request, the greater competition.
Not willing to tell you what they are going to do to optimize your site. There could be 2 options: they will do nothing or going to do something bad.

There are a lot of professional freelancers and companies that provide high quality services. But there are also a lot of pseudo specialists and that can only harm. Therefore, be careful when selecting contractors.
