It's a good idea to use SEO so that the search engines rank your site. If you make any of the following SEO mistakes, it can backfire on you and actually harm your site's ranking.
Many SEO marketers focus their campaigns around the wrong keywords. The reason why it's important to choose the right keywords is simple: people when looking for a certain topic, they'll use a set of keywords. If you want to sell something to people who are training their dogs, target keywords relevant to the niche but also relevant to making a purchase. A dog training ebook should target the keywords "learn dog training." Make an incorrect keyword choice, and it won't matter how good the rest of your marketing plan is. Key to any search engine optimization campaign is a whole list of good keywords for your product and service, so you can get a lot more traffic to your site. There are different options for getting a list of good keywords, but one of the simplest ways is to use quality tools like the Google Keywords tool. One perk to using one of these free keywords tools is that you get good results and don't have to spend a penny. Alternatively, if you're looking for a more customized solution and targeted results, you can go for paid keyword research services like Word Tracker. Last but not the least, make sure that you are absolutely sure about the keywords you target because in the end you don't want to waste a lot of your time optimizing for the wrong keywords and wasting your efforts.
One serious SEO mistake to avoid at all costs is stealing other people's content. If you put your name on someone else's content, you could face legal problems as well as being penalized by the search engines. You are always better off keeping your content unique, as this is what the search engines prefer. They always have the end user in mind, and this means they are looking for content that is not found on other sites. If your content is caught by the search engines' duplicate content filter, it will be excluded from the results. What this is searching for, however, is duplicate content on a single site. There is nothing wrong with using articles that permit you to republish them, as long as the proper credit is given. You will get further in the long run by being honest.
Building a large number of backlinks to your site in a short time is a serious mistake. This is a surefire way of getting the search engines to become suspicious of you. Avoid getting a huge number of links in an unnatural way, and stick to creating them using above board techniques. Improper link building tactics is one of the easiest ways to get penalized by the search engines. The search engines look out for sites that get too many links in a short time, and this shows them that you are using some kind of blackhat strategy. Not a good thing when you're trying to create a lasting relationship with them.
So these are a few of the pitfalls to look out for when it comes to search engine optimization. If you want to be a successful SEO expert, then avoid them and keep an eye out for more.
