Tags or "Metatags" are indexable entries placed on opening webpages for optimizing one's website ranking on major search engines/directories. The optimization process is referred to as "Search Engine Optimization" or "SEO." The following is a discussion on how to place these metatags on one's opening webpage.
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!
