You may want to consider some simple algorithms which, when observed and committed in designing of a website with placement of various critical metatags that can surely achieve a high search engine presence and increase Internet traffic to your website. These metatag strategies work well with published webpages at Google and Yahoo.

Design: Should you create an extensive Flash-based website, make sure to fill-in the property entries such as the Title, Description and Keywords. Failing to do so, leaves no hard HTML or ALT resource that can be readily indexed by search robots.

A non-Flash-based website which relies on hard text, is far easier to be indexed by search robots. Limit the use of stylized text saved as .gifs since as a graphic, they are not indexable by search robots.

Avoid use of frames since any number of search robots are unable to properly classify textual material.

Placement of Metatags:

A ranking or search order does take place with Google and Yahoo and it begins with the "Title" metag which should consist of no more than 65 characters separated by commas. The "Title" should describe in generic terms, the goods and services, followed by a location from which the resource is located, i.e., city, state. The placement of a domain name which is not generic within the "Title" is not appropriate, unless your domain name is a major recognizable brand name.

The second metatag is the "Description" which is usually 25-30 words to form a complete sentence which best describes one’s goods and services.

And the very last category – "Keywords" are also somewhat limited to 15-16 words which can be plural and compound in nature.

Here’s a demonstration of an actual FIRST PAGE placement on Google’s search engine with the submission of very "generic" set of key word queries:
1. Go to Google’s search engine.
2. At the search entry, type in the words "ecommerce tutorials seo" [and of course, leave out the quotes ["]
3. Hit "Enter."
4. There will appear some 1.67 MILLION search results.
5. Check out the No. 2 search entry "Welcome to Downtown L.A." which currently uses the above-referenced algorithms to achieve their FIRST PAGE position.

Good luck!

One way you can prevent (although not eliminate) this possibility is to use social networking sites that have privacy options, which allow you to choose who sees your private information and photographs.

To make sure your better secured, ensure you never post information which compromises your security, such as your national insurance number, credit card details, address, date of birth to websites that do not need it. For example, if a community based website needs your credit card details prior to logging in, then alarm bells should be ringing.

Nothing major is needed, just common sense, and a little knowledge in how fraudsters trick their victims.

There are many online discussion groups, forums, and email discussion lists about marketing. Not surprisingly, the most common topic of discussion is "search marketing," which is really two separate-but-tightly-related activities, "paid search" (ppc, adwords) and "search engine optimization" (seo).

Two groups that I actively read each day are:

LED-Digest http://www.LED-Digest.com/
and
SEM2 http://groups.google.com/group/SEM2

These are both lists primarily for experienced marketers and business owners.

I also participate actively in another community of "affiliate marketers," at:

ABestWeb http://forum.abestweb.com/

Always spend a LOT of time reading any discussion forum or email list before you post; make sure you understand the rules and the community’s common practices.
