Mistakes are a part of our day to day life and they can happen knowingly or unknowingly. Many times we try out things we are confident about and when the results are not as expected we term them as mistakes. Whatever mistakes we make they teach us lot many things. Same principle applies to SEO.

SEO is a vast field and includes many tips and techniques. For any SEO company it is difficult to successfully implement all these techniques into the SEO campaign. There are all possible chances that it might err at some point or the other and the worst part is many times these mistakes go unnoticed.

Some of the common SEO mistakes effecting website ranking can be enumerated as below:

•    Only 10 Meta keywords are allowed for any site. But many sites stuff the Meta with as many keywords as possible. This can decrease the ranking of a site. Meta description should not include more than 150 characters.
•    Many SEO company have large title for the site but in reality the title should be only 70 characters long.
•    The site design should be based on CSS. If HTML is used than the search engines are not able to differentiate between content and design.
•    Just placing images on the site is not done. If you want search engines to consider images for ranking than it is important to support them with alt tag.
•    Webmasters often ignore the longevity of a site. But for search engines it is an important aspect. Domain names with longer registration period are more likely to do well on ranking.
•    On page and off page optimization are equally important. While doing off page optimization do not forget your keywords use them as much as possible in your back links.

If you wish to earn good from your online venture than it is important that you look into all the facets of SEO from meta, title, images, video, content to backlinks, directory submission to social bookmarking.
