Conclusion

Congratulations, you now have a solid (basic) foundation of SEO knowledge. And knowing is half the battle. You already have a step up on the countless masses that have sunk their sweat, tears, and hard-earned money into sites that will never rank well (unless by dumb luck) and will never see their full traffic/conversion/revenue/fame potential.

Search engine optimization is an integral part of online success and should be considered from the very beginning of the website planning process on through to completion, and implemented into your company’s business operations. Whether you decide to hire an SEO company or do it yourself, you have an understanding of the necessary steps every website must perform to achieve search engine greatness.
