The “A HREF Title” attribute is used in text links to add information about the nature of the link. In addition link titles may be spoken by a user agent for users with disabilities.
Sample link title:
<A HREF="ie.html" TITLE="Download Internet Explorer">Click here</a> to download Internet Explorer.
Click here to download Internet Explorer (This is not a real link)
When Internet Explorer users hover the mouse pointer over the link, the link title appears in a tiny floating popup above the link. Don’t worry. It’s not the kind of popup that gets blocked.
There is evidence that using the individual words that comprise your keyword phrase in a page improves relevancy.
You will also likely improve your relevancy for those individual words. For example, if the keyword phrase is "cheap flights," you should sprinkle, "cheap" and "flights" individually throughout the page.
Word stemming is a concept used by some search engines to return search results that include keywords that extend beyond what you searched for.
For example, a search with the keyword "cheap" might return results for, "cheaper" and "cheapest."
In general, try to sprinkle the longer version of keywords throughout a page.
Please note that Google does not use word stemming. So make sure that all variations of your important keywords are included in your webpage.
Keyword Stuffing is the repeating of keywords and keyword phrases in the main body text and Meta tags. Most search engines consider keyword stuffing as spam, so you should never stuff a page with irrelevant keywords in the vain hope of improving your search engine rankings.
Most search engines ignore common words and characters such as "where" and "how," as well as certain single digits and single letters, because they tend to slow down a search without improving the results. It also happens to help to save money by requiring less processing power – the real reason why search engines ignore stop words.
Only full-text search engines, such as AltaVista and Google, index every single word on a webpage.
As such, always try to use keywords instead of stop words as much as possible. Admittedly, some people may find it a bit more difficult to read, but I think it is worth the sacrifice, in the cause of trying to achieve higher search engine rankings.
Here’s a list of the most commonly-used stop words (There are 297 words in the list):
