Long tail keywords, as the adjective indicates, are long keywords with three or more word phrases that are very specific to what you sell. The reason they become effective in SEO is the principle that a user who types long keywords is specifying exactly what he or she wants and thus would most possibly buy from you since the need is urgent. Such searches are more likely to change into sales than the generic one-or-two-word keywords.
Let’s have a look at it with an example. Take the long tail keyword “storage furniture for bedrooms”. Rather than any furniture, the user has asked for “storage furniture”, and rather than storage furniture for any other room in the house, the user needs storage furniture designed specially for bedrooms. This long keyword indicates that the user is in need for this product and upon finding the right product would most probably go ahead and purchase it. The same possibility for sale would be absent if the keyword had been just “furniture” or “storage furniture”. For, in the case of these keywords, the user might just be looking for information or is planning to purchase sometime in future. Long tail keywords could also be questions like “which restaurant serves Italian food in Manchester?” Creating a content page based on these questions can actually increase your traffic from 100 visitors per week to 10,000!
