Search Engine Optimization doesn't require a PhD in Web Technology but it's important that you create a solid plan before you begin. Along those lines, it's absolutely critical that you avoid these three common SEO mistakes.
1. Choosing the wrong keywords
Understanding keywords and how they affect your ability to increase targeted website traffic is paramount . They are the foundation of your SEO efforts and if you choose wrong, you may end up with nothing to show for your hard work!
Conversely, if you optimize each page for intelligent keywords, you'll get an increase in website traffic from those looking for the types of products and services you offer.
2. Disregarding the need to optimize each page
Many novice SEOs optimize the homepage but disregard the rest. Unless your website consists of just one page, this is something you'll want to avoid.
For best results each page of your website should be optimized around 1-3 keyword phrases. This way, you'll improve your chances of getting good rankings (and traffic) across a variety of terms.
It's near impossible to get each page ranked well for dozens of terms. This is why it is so crucial to optimize each and every page.
3. Forgetting to build backlinks
Many website owners mistakenly believe that their website will garner good search engine rankings and attract links without any involvement on their part. While natural links may come over time, you will need to build links yourself if you really want to compete.
After ensuring that you've chosen the right keywords, the building of links should be your number one priority. This activity will do more to improve your ranking in the SERPs than any other.
