Title

The text contained between the start and end HTML tags of the same name. This text is associated with (but not displayed in) the web page containing these tags, and is displayed in a special position (usually at the top of the window) by the web browser.Title text is important because it normally forms the link to the page from the search engine listings, and because the search engines pay special attention to the title text when indexing the page.

Title Tag

The text displayed in the blue bar at the very top of the browser window, above "Back," "Forward," "Refresh," "Print," etc. Although inconspicuous to the user, the title tag is the most important bit of text on a web page as far as the search engines are concerned. Search engines not only assign the words in the title tag more weight, they also typically display the title tag in the search results, making the title tag an important potential call-to-action as well.Thus,the wording of each page's title tag should be thought through carefully.

Tail Terms

Search terms that are very specific, long phrases that include one or more modifiers, such as "cheapest helicopter skiing near Banff BC." These longer, more specific terms are called "tail terms" based on a bell-curve distribution of keyword usage that displays the low numbers of little-used terms at the "tail" end of the bell curve graph. (See "The Long Tail" by wired editor Chris Anderson.) Although long, specific and lesser-used tail terms have low CTRs, they are less competitive (and therefore cheaper) and often catch buyers at the end of the purchase decision process. This means that, even with low click-through numbers, tail terms can have good conversion rates. See also Head Terms.

Targeting

Narrowly focusing ads and keywords to attract a specific, marketing-profiled searcher and potential customer. You can target to geographic locations (geo-targeting), by days of the week or time of day (dayparting), or by gender and age (demographic targeting). Targeting features vary by search engine. Newer ad techniques and software focus on behavioral targeting, based on web activity and behaviors that are predictive for potential customers who might be more receptive to particular ads.

Trademarks

Tier I search engines prohibit bids on trademarks as keywords if the bidder is not the legal owner, though this keyword bid practice is still allowed by Google.
