STRONG>DO NOT repeat keywords in your Meta Tags, e.g.: BeOnTop,BeOnTop,BeOnTop,BeOnTop. This type of practice is regarded as Spamming by most of the search engines and can result in the eventual banning of your site altogether. See also 'Word Scrambled' and 'Keyword Stuffing'.

DO NOT try to include every possible keyword in the dictionary. The more keywords that you include, the more chance you have of 'diluting' the perceived relevancy of these words. This kind of practice may result in a downgrading of your web page Ranking on some important search engines.

Aim to use more grammatically correct sentences in your Meta Tags, ie: in your Page Title and Description, rather than just a simple list of keywords.
