How to get your website ranked on search engines

There are many factors involved in getting your website ranking on search engines. Below are some key things to take into consideration, and we hope that it will help you to increase traffic on your blog website or forum 

Anchor text
The anchor text of inbound links coming to your website is very important as search engines use this to determine what your site is about and what it should rank well for. Your anchor text should be your keywords that you want your website to rank for. For example, instead of using your company name or your website URL for inbound links, consider using keywords as your anchor text.

Use keywords in your title tag and other meta tags
Meta tags still have an impact on where your website will rank on search engines. The weight of the meta tags may be minimal, but it is still recommended that you choose keywords relevant to each webpage. It is an effective way for search engines to categorise your webpages and gives search engine spiders an idea of what your webpage is about.

Links to your website
The largest factor that influences search engine rankings is the number and quality of links that are pointing to your website. The more quality links that you have coming to your website, search engines will think your website has authority.

Keyword use in the root domain
Although it's possible to use subdomain or dedicated pages to get your keywords in a URL, nothing beats having your keywords in your domain name. For example, goldcoastaccommodation.com.au.

Apply the proper tags to your page
This means using H1, H2, and H3 tags in your headings and sub-headings.

Include a html sitemap and an xml sitemap on your website
Including a sitemap on your website makes it easy for search engine spiders to access all your webpages and index your site accordingly.

Make sure all images have an ALT text
Your image alt text is read by search engine spiders, so make sure you include keywords in your alt text. Label your images properly too, for example, instead of calling it bedroom.jpg, call it melbourne-accommodation-1-bedroom-apartments.jpg.

Lock/Unlock Your Computer With Pendrives

SYSKEY is a utility that encrypts the hashed password information in a SAM database in a Windows system using a 128-bit encryption key.

SYSKEY was an optional feature added in Windows NT 4.0 SP3. It was meant to protect against offline password cracking attacks so that the SAM database would still be secure even if someone had a copy of it. However, in December 1999, a security team from Bind  View found a security hole in SYSKEY which indicates that a certain form of cryptanalytic attack is possible offline. A brute force attack then appeared to be possible.

Microsoft later collaborated with Bind View to issue a fix for the problem (dubbed the ‘Syskey Bug’) which appears to have been settled and SYSKEY has been pronounced secure enough to resist brute force attack.

According to Todd Sabin of the Bind View team RAZOR, the pre-RC3 versions of Windows 2000 were also affected.

So this is pretty cool, right?  Well, I really like the idea of keeping this on Floppy so that it requires a floppy disk (a sort of 2 factor (hardware/software) authentication?).

Naturally I wanted to go a bit further and use this on a USB drive instead of storing to a Floppy.  I can’t see myself carrying a floppy and a USB floppy drive around with me.  After all, this provides another layer of security.

NOTE:  I haven’t tested copying data from 1 USB to another USB to see if it works as a backup.  This way you could lock up a USB drive as a spare if needed.

Here’s how to get this to work using a USB drive.

1.  Insert your USB drive into your system and wait for it to be recognized and install any necessary drivers.

2.  Fire up disk management and re-assign the drive letter it was given to “A”.

Start up disk management by clicking Start and typing diskmgmt.msc

Right-click the USB drive and choose to assign driver letter or path.

Assign it to letter “A”

Accept the warning message

Now your USB drive is “A”

3.  Run Syskey and save encryption to USB Drive “A”

Click Start and type syskey followed by hitting Enter

Syskey launched; Click “Update”

Choose “Store Startup key on floppy disk” and click “OK”

You’ll be prompted to enter your diskette. Make sure your USB drive is inserted and writable.

4.  Reboot and have fun.  Don’t lose your USB disk!  Also, to revert this, you can run syskey again and choose to store it locally instead of “on a floppy disk”.

10 Reasons why PC’s Crash You Must Know.

Fatal error: The system has become unstable or is busy," it says. "Enter to return to Windows or press Control-Alt-Delete

to restart your computer. If you do this you will lose any unsaved information in all open applications."

You have just been struck by the Blue Screen of Death. Anyone who uses Microsoft Windows will be familiar with this.

What can you do? More importantly, how can you prevent it happening?

1. Hardware conflict -

The number one reason why Windows crashes is hardware conflict. Each hardware device communicates to other devices

through an interrupt request channel (IRQ). These are supposed to be unique for each device.

For example, a printer usually connects internally on IRQ 7. The keyboard usually uses IRQ 1 and the floppy disk drive IRQ

6. Each device will try to hog a single IRQ for itself.

If there are a lot of devices, or if they are not installed properly, two of them may end up sharing the same IRQ number.

When the user tries to use both devices at the same time, a crash can happen. The way to check if your computer has a

hardware conflict is through the following route:

* Start-Settings-Control Panel-System-Device Manager.

Often if a device has a problem a yellow '!' appears next to its description in the Device Manager. Highlight Computer (in

the Device Manager) and press Properties to see the IRQ numbers used by your computer. If the IRQ number appears

twice, two devices may be using it.

Sometimes a device might share an IRQ with something described as 'IRQ holder for PCI steering'. This can be ignored.

The best way to fix this problem is to remove the problem device and reinstall it.

Sometimes you may have to find more recent drivers on the internet to make the device function properly. A good

resource is www.driverguide.com. If the device is a soundcard, or a modem, it can often be fixed by moving it to a

different slot on the motherboard (be careful about opening your computer, as you may void the warranty).

When working inside a computer you should switch it off, unplug the mains lead and touch an unpainted metal surface to

discharge any static electricity.

To be fair to Microsoft, the problem with IRQ numbers is not of its making. It is a legacy problem going back to the first PC

designs using the IBM 8086 chip. Initially there were only eight IRQs. Today there are 16 IRQs in a PC. It is easy to run out

of them. There are plans to increase the number of IRQs in future designs.

2. Bad RAM -

RAM-(random-access memory) problems might bring on the blue screen of death with a message saying Fatal Exception

Error. A fatal error indicates a serious hardware problem. Sometimes it may mean a part is damaged and will need

replacing.

But a fatal error caused by Ram might be caused by a mismatch of chips. For example, mixing 70-nanosecond (70ns) Ram

with 60ns Ram will usually force the computer to run the entire Ram at the slower speed. This will often crash the

machine if the Ram is overworked.

One way around this problem is to enter the BIOS settings and increase the wait state of the Ram. This can make it more

stable. Another way to troubleshoot a suspected Ram problem is to rearrange the Ram chips on the motherboard, or take

some of them out. Then try to repeat the circumstances that caused the crash. When handling Ram try not to touch the

gold connections, as they can be easily damaged.

Parity error messages also refer to Ram. Modern Ram chips are either parity (ECC) or non parity (non-ECC). It is best not

to mix the two types, as this can be a cause of trouble.

EMM386 error messages refer to memory problems but may not be connected to bad Ram. This may be due to free

memory problems often linked to old Dos-based programs.

3. BIOS settings -

Every motherboard is supplied with a range of chipset settings that are decided in the factory. A common way to access

these settings is to press the F2 or delete button during the first few seconds of a boot-up.

Once inside the BIOS, great care should be taken. It is a good idea to write down on a piece of paper all the settings that

appear on the screen. That way, if you change something and the computer becomes more unstable, you will know what

settings to revert to.

A common BIOS error concerns the CAS latency. This refers to the Ram. Older EDO (extended data out) Ram has a CAS

latency of 3. Newer SDRam has a CAS latency of 2. Setting the wrong figure can cause the Ram to lock up and freeze the

computer's display.

Microsoft Windows is better at allocating IRQ numbers than any BIOS. If possible set the IRQ numbers to Auto in the BIOS.

This will allow Windows to allocate the IRQ numbers (make sure the BIOS setting for Plug and Play OS is switched to 'yes'

to allow Windows to do this.).

4. Hard disk drives -

After a few weeks, the information on a hard disk drive starts to become piecemeal or fragmented. It is a good idea to

defragment the hard disk every week or so, to prevent the disk from causing a screen freeze. Go to

* Start-Programs-Accessories-System Tools-Disk Defragmenter

This will start the procedure. You will be unable to write data to the hard drive (to save it) while the disk is defragmenting,

so it is a good idea to schedule the procedure for a period of inactivity using the Task Scheduler.

The Task Scheduler should be one of the small icons on the bottom right of the Windows opening page (the desktop).

Some lockups and screen freezes caused by hard disk problems can be solved by reducing the read-ahead optimization.

This can be adjusted by going to

* Start-Settings-Control Panel-System Icon-Performance-File System-Hard Disk.

Hard disks will slow down and crash if they are too full. Do some housekeeping on your hard drive every few months and

free some space on it. Open the Windows folder on the C drive and find the Temporary Internet Files folder. Deleting the

contents (not the folder) can free a lot of space.

Empty the Recycle Bin every week to free more space. Hard disk drives should be scanned every week for errors or bad

sectors. Go to

* Start-Programs-Accessories-System Tools-Scandisk

Otherwise assign the Task Scheduler to perform this operation at night when the computer is not in use.

5. Fatal OE exceptions and VXD errors -

Fatal OE exception errors and VXD errors are often caused by video card problems.

These can often be resolved easily by reducing the resolution of the video display. Go to

* Start-Settings-Control Panel-Display-Settings

Here you should slide the screen area bar to the left. Take a look at the colour settings on the left of that window. For

most desktops, high colour 16-bit depth is adequate.

If the screen freezes or you experience system lockups it might be due to the video card. Make sure it does not have a

hardware conflict. Go to

* Start-Settings-Control Panel-System-Device Manager

Here, select the + beside Display Adapter. A line of text describing your video card should appear. Select it (make it blue)

and press properties. Then select Resources and select each line in the window. Look for a message that says No Conflicts.

If you have video card hardware conflict, you will see it here. Be careful at this point and make a note of everything you

do in case you make things worse.

The way to resolve a hardware conflict is to uncheck the Use Automatic Settings box and hit the Change Settings button.

You are searching for a setting that will display a No Conflicts message.

Another useful way to resolve video problems is to go to

* Start-Settings-Control Panel-System-Performance-Graphics

Here you should move the Hardware Acceleration slider to the left. As ever, the most common cause of problems relating

to graphics cards is old or faulty drivers (a driver is a small piece of software used by a computer to communicate with a

device).

Look up your video card's manufacturer on the internet and search for the most recent drivers for it.

6. Viruses -

Often the first sign of a virus infection is instability. Some viruses erase the boot sector of a hard drive, making it

impossible to start. This is why it is a good idea to create a Windows start-up disk. Go to

* Start-Settings-Control Panel-Add/Remove Programs

Here, look for the Start Up Disk tab. Virus protection requires constant vigilance.

A virus scanner requires a list of virus signatures in order to be able to identify viruses. These signatures are stored in a

DAT file. DAT files should be updated weekly from the website of your antivirus software manufacturer.

An excellent antivirus program is McAfee Virus Scan by Network Associates (www.nai.com). Another is Norton Antivirus

2000, made by Symantec (www.symantec.com).

7. Printers -

The action of sending a document to print creates a bigger file, often called a postscript file.

Printers have only a small amount of memory, called a buffer. This can be easily overloaded. Printing a document also

uses a considerable amount of CPU power. This will also slow down the computer's performance.

If the printer is trying to print unusual characters, these might not be recognised, and can crash the computer. Sometimes

printers will not recover from a crash because of confusion in the buffer. A good way to clear the buffer is to unplug the

printer for ten seconds. Booting up from a powerless state, also called a cold boot, will restore the printer's default

settings and you may be able to carry on.

8. Softwares -

A common cause of computer crash is faulty or badly-installed software. Often the problem can be cured by uninstalling

the software and then reinstalling it. Use Norton Uninstall or Uninstall Shield to remove an application from your system

properly. This will also remove references to the programme in the System Registry and leaves the way clear for a

completely fresh copy.

The System Registry can be corrupted by old references to obsolete software that you thought was uninstalled. Use Reg

Cleaner by Jouni Vuorio to clean up the System Registry and remove obsolete entries. It works on Windows 95, Windows

98, Windows 98 SE (Second Edition), Windows Millennium Edition (ME), NT4 and Windows 2000.

Read the instructions and use it carefully so you don't do permanent damage to the Registry. If the Registry is damaged

you will have to reinstall your operating system. Reg Cleaner can be obtained from www.jv16.org

Often a Windows problem can be resolved by entering Safe Mode. This can be done during start-up. When you see the

message "Starting Windows" press F4. This should take you into Safe Mode.

Safe Mode loads a minimum of drivers. It allows you to find and fix problems that prevent Windows from loading

properly.

Sometimes installing Windows is difficult because of unsuitable BIOS settings. If you keep getting SUWIN error messages

(Windows setup) during the Windows installation, then try entering the BIOS and disabling the CPU internal cache. Try to

disable the Level 2 (L2) cache if that doesn't work.

Remember to restore all the BIOS settings back to their former settings following installation.

9. Overheating -

Central processing units (CPUs) are usually equipped with fans to keep them cool. If the fan fails or if the CPU gets old it

may start to overheat and generate a particular kind of error called a kernel error. This is a common problem in chips that

have been over clocked to operate at higher speeds than they are supposed to.

One remedy is to get a bigger better fan and install it on top of the CPU. Specialist cooling fans/heat sinks are available

from www.computernerd.com or www.coolit.com

CPU problems can often be fixed by disabling the CPU internal cache in the BIOS. This will make the machine run more

slowly, but it should also be more stable.

10. Power supply problems -

With all the new construction going on around the country the steady supply of electricity has become disrupted. A power

surge or spike can crash a computer as easily as a power cut.

If this has become a nuisance for you then consider buying a uninterrupted power supply (UPS). This will give you a clean

power supply when there is electricity, and it will give you a few minutes to perform a controlled shutdown in case of a

power cut.

It is a good investment if your data are critical, because a power cut will cause any unsaved data to be lost.
