When we mention about SEO, most of us will probably feel headache, including me. And, those question loomed up in our mind are the almost alike—— 'How am I going to be top ranked?', 'When will I be on top of others in this niche...and bla bla blaa' Those questions are annoyed, and bothered most of us. If you have followed those steps to fit with the algorithm of the search engines, then probably you have a better chance in getting top-ranked than others who don't. However, most of us made a few mistakes when blogging that we don't even realize sometimes. These matters a lot in getting you top ranked, or even push you out of the thousandth ranking.

Mistakes

Grammar mistakes

Content of your page are important. Your contents are not only read by humans, but also search engines. Search engines crawlers are not humans, they don't have the ability to see pictures, and text is the merely way for them to understand your content well. If there are grammar mistakes in your contents, then how can crawlers understand well your contents are about and how to give you a good ranking in search results.

Over-stuffing keywords

Over-stuffed your contents with keywords is a big deal. It bothers your reputation to the search engines. Let's say if you write contents with 'SEO' keywords and 'SEO' occupied 50% of your contents, most likely you will get penalty. It looks exaggerated, but this is what someone else did. If the content are stuffing keywords, for a human-readers, also may feel gross. Definitely, your reputations will decline as well.

Keywords misspelled

This case is mostly similar with grammar mistakes. But, this mistake brings you more trouble than grammar mistakes. A little bit of grammar mistakes may be forgiven, but keywords misspelled are big problems. If you're optimizing ‘dog care, but you misspelled it as 'dog core', and in common sense, who know what is ‘dog core’. If even humans do not understand what are you writing about, and so is a search engine crawler (a machine). Maybe a little misspelled are acceptable, but try to avoid these careless mistakes.

Alt-text for images

Alt-text for images is important in SEO as I have mentioned frequently, though it's not as important as title,contents and url. An alt-text will help you in SEO when you used it wisely and rightfully. On the contrary, abusing it may bring you troubles too. Don’t over-stuffed keywords that are not related. Give a best-suitable name for the images, and do not stuffed keywords into it.

Duplicated contents

Everyone knows copying is wrong. Do not even try to duplicate someone else’s contents provided if the webmasters are giving you permission to do so. If they do give you permission, don't make it 100% alike, or even 80%. Crawler doesn't know, and don't usually judge (a machine don't judge). If you copy, then it's definitely, offending the algorithm.

However, there are ways to overcome this problem. Try to collects information, and put your ideas into it and then produce your own original and genuine articles.
