Exactly---the concept of article writing is to improve your site in
terms of how it`s relevant to people and their own lives. For example,
in today`s world we have a lot of stress about gas prices. That stress
fits into the topic of "Stress." Chiropractics features the
apprehension and care of stress-related effects on the body.
So an article about how chiropractics can help cope with the stress of
gas prices would make it relevant to your site. Now suppose someone
does a query in Google about "coping with high gas prices." When your
article has been indexed, it would show as having strong "relevance"
(Google`s mission in life) to that query.
In other words, your site would show up in some or another level---your
ranking. That increases your visibility. If two chiropractic sites are
both pretty much equal, both in the same geographic area, and both
offer about the same brand, the one people see first likely will take
more market share.
Your efforts on Web marketing are toward visibility---being seen by more people.
As for loading time....that`s a technical issue beyond my basic understanding of developing Web sites.
