As someone who sells SEO as a service it is often not in my best interest to tell people they can do SEO on their own. But it’s true. Just as changing the car’s oil, fixing clogged pipes, or painting a house are all relatively easy, most business owners can SEO their website on their own. All it takes is some knowledge and time.
Knowledge can be found easily enough for free, and time, well, that’s not something you likely have an excess of. Fortunately, SEO doesn’t all have to be done at once, it can be implemented a little at a time, as you have time.
