That’s the best answer that I can give you. And anyone who tells you otherwise is leading you on.
Just look at what happened to Expedia starting last week. They tried to boost their search rankings on the top search engine in a way that goes against Google’s policies. And they are paying the ultimate penalty.
Yes, it is possible to “trick” search engines like Google into ranking you higher. And many SEO or marketing firms will tell you that they know the tricks in order to get your business. But as soon as Google catches you “gaming” the system, they will manually drop or eliminate your rankings altogether. And you will lose a vital source of traffic to your website.
That does not mean SEO best practices should be ignored. Learn what they are, then learn the rules, and play by them.
