Search Engine Optimization

Following suggestions may help you make your website search engine friendly.

1. Design: Ensure that design issues do not prevent the search engines from ranking your site. Some of the common problems with design that may interfere with the way the search engines work are:

* Use of frames and layers and http calls,
* Dynamic display of data,
* Dynamic use of urls and page executions to display pages. For example Google advises you not to use "&id=" as a parameter in your URLs as they would not include such pages in their index.
* Use of flash menus, and image maps (hot keys) for navigation,
* Use of client side (javascripts) and server side programs, Database and SQL scripts for navigation and other functions.
* Use of session ids or parameters that would prevent the search bots from crawling through your site.

2. Keywords: Select right keywords, that are specific and appropriate for your site. Much better if the keywords are found in the body tag of the page you are optimizing. Do some bench mark studies to see what keywords are being used by other websites that are similar to yours in content. Imagine what search words users might enter in the search engines to get the content that is similar to what you are providing and use the same phrases as your keywords. Find the right mix and balance of keywords, neither more nor less (max about 1000 characters) and do not use the same keyword more than once.

3. Title: Limit the title length to a few words or about 75 characters (including the spaces). Use in your title one or two keywords from the page keyword meta-tag.

4. Text on the Page: Technically this is the content you provide in the body tag and what your site visitors get to see on each page. From optimization point of view, what you provide in the body tag of the web page is as important as the meta tags and the title of the page. Make sure that there are at least 200 to 300 words in your body tag and that some of the keywords used in the meta tag are also found the body tag.

5. Meta tags: Use appropriate meta tags in addition to the keyword meta tag. Meta tags help the robots to decide how to index your site and they are usually the first lines in a page to be read by them. So use meta tags generously in each page. Make sure that you will use at least the , , , , meta tags. The description tag is very important. It should have some of the keywords you use for the page and reflect the summary of the information in the body tag. It length should be around 250 characters including space.

6. Robots.txt: Create a robots text file preferably with a notepad and place it in the root folder of your website. A robots text file usually contains directions to be followed by the robots especially what directories and files on your site to be indexed or not indexed. This small text file with a few lines of code is important because whenever robots visit your site to index your site they will look for this file for general directions. If you want to know how to create robots text file and what directions you need to provide please follow the link provided here.

7. Images: From a search engine point of view, each image in your page is a file by itself and when they come across image tags in a page during indexing they index the images separately. Search engines like Google now a days index images separately and provide an option to the users to search for graphics exclusively. It is therefore important that you provide appropriate information about each image in the 'alt' tag. The following example shows how you can do it:



8. Miscellaneous suggestions: In addition to the above keep in mind the following do's and don'ts.

* Avoid using multiple pages with the same title and description.
* Do not use hidden messages using the same colored font as the background in the page to trick the search engines.
* Do not repeat the keywords and titles in the same page. Also use only one meta tag for all your keywords.
* Use relevant keywords and phrases.

Tricks of Cheap Webhosting Services

If you thought all those billions of web pages are hosted on expensive and full service web hosting companies, you need to cross check your information sources again. Of course, there are free or cheap web hosting companies that provide basic features good enough for simple html pages. You can take the example of some blog sites for these. But cheap (as cheap as $1.99 a month) web hosting service is different as they claim to provide more than the basic features which require huge infrastructures and funds to maintain and remain in the business. How do cheap web hosting companies attract business and what are their tricks?

Trick Number 1: The 24/7 toll-free number that a cheap web hosting company will advertise on their website. Most of these rarely work and those that do work seem to work only Monday to Friday. They are there mainly to create a false impression. What will you do on the weekend or after hours? You need a web hosting company that provides real support.

Trick Number 2: E-mail contacts given, which give you a very nicely worded (auto responder) response, requesting you to be patient while promising that an appropriate web hosting executive is handling your query. Don't you want to talk to a real person at some point? Email messages could go on forever with no resolution in sight. Your time, in short supply, is valuable.

Trick Number 3: Unlimited emails in POP3 and SMTP which hardly give any value to a small webmaster but can have a big impact on your decision making. Cheap web hosting companies cannot provide good email service. Yet, you need good email service so that you can stay in contact with your customers. (better service=more customers=more sales)

Trick Number 4: Cheap web hosting companies often make promises of free downloads worth thousands of dollars. You can check this offer only after you subscribe to their service. You should be able to check out all aspects of an offer before making a commitment, thus saving you valuable time and money.

Computer Memory

A computer uses two types of storage devices called primary and secondary storage devices. The difference between the two is that the primary storage devices hold are essentially temporary storage devices where information lasts for a short period where are secondary storage devices allow the storage of information for much longer period, till either it is removed or modified by some external means. The Central Processor in the computer (CPU) can access the primary storage directly but cannot interact with the secondary storage directly. To do information has to be first loaded into the primary storage devices where it would be processed before being sent back or directed elsewhere.

Primary storage devices are more popularly called memory chips or RAM (Random Access Memory) chips. The chips hold both instructions and data temporarily to enable the central processing unit carry out different tasks and keep the computer running. The RAM is basically of two types: dynamic RAM also called DRAM and static RAM also called SRAM. DRAM holds information for a very short time, while SRAM holds it as long as the power is not turned off. Both hold information temporarily but SRAM holds a bit longer.

In older computer RAM chips used to exist as individual chips embedded in the system board in rows of nine chips each. Each of the eights chips held one byte of memory while the ninth one, called a parity chip, held a parity bit. The parity chip played a key role by keeping the computer from crashing by maintaining the integrity of the bits stored in the other eight chips.

In later day computer models RAM chips got organized into SIMMs or single inline memory modules. A SIMM consisted of a single mini board with several chips and 30 or 72 pins on its edge. A SIMM can hold from 8 MB to 64 MB of RAM on a single board. Since RAM is now located on detachable mini boards, it is easier to upgrade RAM by adding more SIMMs.

The most popular form memory module used in computers today is DIMM or Dual inline memory module. While a SIMM has a data path of 32 bits, a DIMM has a data path of 64 bits. DIMMs are generally available in 8 MB, 16 MB, 32 MB and 64 MB sizes, but it is not uncommon to find DIMMs in Gigabytes of memory. DIMMs are available with varying number of pins from 72-pin-DIMMs, used for SO-DIMM to 240-pin-DIMMs, used for DDR2 SDRAM.
