Today, there are thousands of people who want to rank high in search engines, and undoubtedly SEO work is done for many sites, from professional companies to personal works. Just like in everyday life, these works can be done by good-hearted and malicious people who can resort to any kind of trick to reach a quick solution. Today, Google tries to examine the pages it scans just like a human being thanks to the software it uses and improves its algorithms in this direction day by day. The main reason why Google gives such reliable results and is preferred by millions of people is that it correctly filters how much the sites appeal to visitors, considering the keywords searched. In other words, SEO is actually presenting the right documents to the target audience we have determined, not to the spiders. Professional web design agencies know this difference and create a design and content plan suitable for Google's spiders by working according to their target audience before starting their projects.
