SEO has three parts. Technical SEO makes sure search engines can read the site and pages load fast. Content answers what people actually search for. Links build trust through mentions and links from other sites.
What to expect
SEO is a long game. First results come after months, not days. Unlike ads, though, the traffic does not stop the day you stop paying.
What to avoid
Promises of the number one spot for a given keyword, buying links in bulk and copy written for the search engine instead of people. Google has learned to spot it.
