Keywords selected for a website can be placed over a number of places in the HTML of the website. Placing keywords in title and description Meta tags of a web page plays an important part in proper and strategic placement of researched keywords.
Web page title and description might not be the most important factors to fight the complex algorithms of search engine rankings but they are among the top factors to drive visitors to a website from search engines. Search engines display the title and description of a website in search results and visitors are always attracted to some well versed and descriptive titles.
Descriptive Titles
Longer and descriptive titles play an important role in driving a search engine user to visit the website. Most users only read the titles of websites that appear in search results and decide if that website is providing what they are looking for. It's just like reading a newspaper or a magazine; First, the headlines are read and then some excerpts of the entire news article and then we decide if the article is interesting or not.
Titles and description should be a combination of eye catching words. Using all CAPS is never recommended as it's a little difficult to read such sentences. Providing ease to a user increases the usability of a website and chances of a high click through rate are immense.
Recommendations
Research your keywords and keyword competition properly. You must know what are the most effective and result oriented keywords for your website. Place these keywords in a descriptive form in title and description. Consider yourself a search engine user and then think what would be the most effective phrase for you to click over a search result and visit that website.
Use long tail titles for your website. Instead of focusing yourself over one or two words keywords, focus on the term or phrase that would be used as a search query. That phrase will ultimately have all your one or two words keywords within it as well and this will highly improve your search engine ranking.
Search engine optimization has become a complex process and to get a better search engine ranking needs all factors to be considered. These factors are not just limited to website titles, other meta tags and content of the website have the same importance.
