Why do companies start with SEO tricks on to? is the main reason why, because the method of search engine spamming often less time consuming as a serious SEO question. We know the yes: If you want to populate a website with relevant keywords, is not only time but also often expensive to create those keywords optimized content.
As example would be the method with the page template: Here you can collect revenue by thousands of doorway pages for search terms and does not even content with relevant keywords manually populate. Often it also happens that companies want to shape the content of their website so worded that they are recognized as in-house.
The analogy of the content on search engines with regard to the language of the prospective clients is problematic. So it seems to be that not only informative content is created for the site, but also content that is only created, so that search engines can access it. This is generally regarded as spamming already! But it happens just that the owner of a site entrusted to an agency, and in good faith assumption that these reputable SEO agency is working and does not need tricks.
And it is not easy to see through at first glance if the SEO agency has been working seriously or has used search engine spamming. Many see search engine spamming still as a minor offense. For many sites make the search engine spamming their own and are not aware of the risks in order to fall on the nose. They do not seem to consider that search engine spamming can have drastic consequences.
