Link Exchange and Link Trading
Certain SEO strategies try to exploit certain rules of search robots. Web-sites utilizing these are being penalized by search engines.
One of the most common strategies resemble SPAM. Some Search Engine Optimization 'Specialists' will offer, for certain amount of money, hundreds of links to your web-site coming from other web-sites, or others that offer massive link exchange or massive link trading. These web-sites are called link farms, as there sole purpose is providing hundreds of links to other web-sites. These SEO 'experts' know that number of links is one of many factors for increasing web-page rank in search results. However, they don't want to invest time and effort on doing real Search Engine Optimization by improving other 100+ factors, like for example content of your pages. They just want to make fast money by increasing your site's ranking by linking to it from the SPAM sites.
Once search engines detect this, your site will be penalized, and its position will fall below the level it would have if it didn't have any of these links! Avoid these scam SEO's.
If you have new website with original idea or if you are in a competitive business where top search results return pages with PageRanks 4 and up (for example: Chicago real estate), then web-site SEO may not be enough. If this is the case, this company will help qualified clients with a high PageRank page on this web-site. This is far better solution than link exchange or link trading. This page here will have better effect than linking from hundreds of low grade sites. Not only you will have an excellent page to put your content on, but will also be able to link to your web-page from it, which will also rise your PageRank to almost half that level. Note that since PR is a logarithmic scale, half of 5 is not 2.5 but is somewhere between 4 and 5 (it may still be 5!).

Note that PR increase by itself won't be enough. Real content SEO writing is necessary for a web page to appear on top of search engine results.
