You can rank on Google without links
A lot of search marketers put an emphasis on links, and they are important. However, it is possible to rank a website without links. There are other things that are massively important to a website's rankings. These include things like website technicality and site speed. If your on-site SEO is perfect, it is possible to rank for certain search terms without links.
SEO is nothing more than placing free ads on Google.
I'm sure you've seen freeads sites like Gumtree and Preloved. Google is just like that. Google is just a place for free ads on the internet. Although Google does have an algorithm and it can be quite complicated, there isn't some kind of secret magic formula that you need to follow in order to rank your website well.
Internet Marketing is easier now than it has ever been
Nowadays it's much easier to market a website than it has ever been. One reason for this is the fact that there is a seemingly endless amount of literature out there that can help you on your way. Not only that but there are more avenues now than ever before. One example of this is Facebook marketing. Although not new, it's a great way for you to reach target audiences.
Top positions in search engines are not in concrete
When you do a web search for something that you sell and see the top search results, these results are not permanent. With the right knowledge or the right person in charge of your campaigns, you can get yourself up there in the rankings. Although this is the case, some sites are harder than others to replace - sites such as Wikipedia, Google, Facebook and other internet giants.
