The long term keyword phrase info doesn’t really need a refreshing for 2015.
Long tail keyword phrases are consumer keyword phrases, usually containing 3 or more words, with which a search engine user will focus their query in order to obtain more relevant results.
Querying “Bathroom Fixtures” yields a variety of manufacturers and retail locations.
“Kohler Bathroom Fixtures Boston” may yield very different results and be an applicable long tail phrase if you sell that certain brand of bathroom fixture from a showroom in the Boston area.
Adding the following emphases to important phrases can be helpful.
underline or italic
bolden your long tail keyword phrase
These emphases make the phrases more noticeable to users and search-bots.
