Long-tail keywords are keywords of two to six words in length. These long-tails find increased click-through-rates (CTR), increased relevant organic traffic, decreased Pay-Per-Click (PPC) costs, and less competition for ranking in search spaces.
The reason is simple, competition decreases significantly per each word added to any string of keywords, while relevance to the consumer who is searching for the long-tail increases. These are niche areas.
Once long-tail keywords are identified, or rather consumer search niches are found, integrate them via us of a keyword strategy. By doing so, your site will rank higher in search results, and thus position your content organically in results. This should increase both click through rates (CTRs) and conversions.
Keyword strings low in competitiveness also have lower pay-per-click costs, and they will decrease irrelevant or uninterested through traffic on your PPC ads.
