Understand the right meaning of "hot" keywords! These are NOT the miracle-ones (mesothelioma, asbestosis or others like these) but are the smartly-chosen ones. The art is how to choose and use them. Monetize "hot" keywords! But how? Surely not by building sites around high-paying keywords! It's a huge mistake and we'll explain further why.
Optimize Your Keyword Content
The number of occurrences of keywords in the content should be enough to make the content theme-relevant. But keep them coming naturally in the content, do not overdo it. ◦The key-positions should be: title, description tag, headings, URL, a top-page position. Proximity to the AdSense™ code seems to get weighted more heavily.
◦Also keywords should appear bolded and in italics.
◦Increase the number of keywords in the plural. Google ranks plurals separately.
◦Ensure a keyword density between 5 and 20%. You can check this with the help of a keyword tracker.
◦Anchor texts should include keywords.
◦Stick to one main theme per page. Better more pages with just one or two related keywords per page than one long page.
HIGHLY DESCRIPTIVE FILE NAMES can be very effective (this is applicable to new pages that are not yet in the search engines, for changing the name of an older one may result in losing traffic).
Sometimes, the THEME OF THE EXTERNAL SITES you link to MATTERS for the relevance of your own ads. You may try to place relevant links near your ads.
RELEVANT DOMAIN NAMES have an influence on Google's choice of ads.
