It is the search engines that finally bring your website to the notice of the prospective customers. When a topic is typed for search, nearly instantly, the search engine will sift through the millions of pages it has indexed about and present you with ones that match your topic. The searched matches are also ranked, so that the most relevant ones come first.

Remember that a prospective customer will probably only look at the first 2-3 listings in the search results. So it does matter where your website appears in the search engine ranking.

Further, they all use one of the top 6-7 search engines and these search engines attract more visitors to websites than anything else. So finally it all depends on which search engines the customers use and how they rank your site.

It is the Keywords that play an important role than any expensive online or offline advertising of your website.

It is found by surveys that a when customers want to find a website for information or to buy a product or service, they find their site in one of the following ways:

1. • The first option is they find their site through a search engine.
2. • Secondly they find their site by clicking on a link from another website or page that relates to the topic in which they are interested.
3. • Occasionally, they find a site by hearing about it from a friend or reading in an article.

Thus it’s obvious the the most popular way to find a site, by search engine, represents more than 90% of online users. In other words, only 10% of the people looking for a website will use methods other than search engines.

All search engines employ a ranking algorithm and one of the main rules in a ranking algorithm is to check the location and frequency of keywords on a web page. Don’t forget that algorithms also give weightage to link population (number of web pages linking to your site). When performed by a qualified, experienced search engine optimization consultant, your site for high search engine rankings really does work, unless you have a lot of money and can afford to pay the expert. With better knowledge of search engines and how they work, you can also do it on your own.

Referrer logging is used to allow web servers and websites to identify where people are visiting them either for promotional or security purposes. You can find out which search engine they used to find your site and whether your customer has come from a ‘linked site’. It is basically the URL of the previous webpage from which your link was followed.

By default, most hosting accounts don’t include referrer logs but may be subscribedd for an extra monthly fee. If your web host does not provide a graphic report of your log files, you can still view the referrer logs for your website by logging into the host server using free or low-cost FTP software, like these:

FTP Explorer: http://www.ftpx.com/
LogMeIn: http://secure.logmein.com/dmcq/103/support.asp
SmartFTP: http://www.smartftp.com/
FTP Voyager: http://www.ftpvoyager.com/

The log file is available on your web server which can be download into your computer later. You can use a log analysis tool, like those mentioned below, to create a graphic report from your log files so that the files are easier to understand.

Abacre Advanced Log Analyzer http://www.abacre.com/ala/
Referrer Soft http://www.softplatz.com/software/referrer/
Log Analyzer http://www.loganalyzer.net

You can view the files using Word, Word Perfect, txt or WordPad files even if you don’t have the right tool. This information is very crucial to your business and marketing plans and is not advisable to neglect it.

In addition to identifying the search engine or linked site from where your visitor arrived, referrer logs can also tell you what keywords or keyword phrases your client used for searching.

As referrer information can sometimes violate privacy, some browsers allow the user to disable the sending of referrer information. Proxy and Firewall software can also filter out referrer information, to avoid leaking the location of private websites. This can result in other problems, as some servers block parts of their site to browsers that don’t send the right referrer information, in an attempt to prevent deep linking or unauthorized use of bandwidth. Some proxy software gives the top-level address of the target site itself as the referrer, which prevents these problems and still not divulging the user’s last visited site.

Since the referrer can easily be spoofed or faked, however, it is of limited use in this regard except on a casual basis.

It is worth cataloguing the basic principles to be enforced to increase website traffic and search engine rankings. 

• Create a site with valuable content, products or services.
• Place primary and secondary keywords within the first 25 words in your page content and spread them evenly throughout the document.
• Research and use the right keywords/phrases to attract your target customers.
• Use your keywords in the right fields and references within your web page. Like Title, META tags, Headers, etc.
• Keep your site design simple so that your customers can navigate easily between web pages, find what they want and buy products and services.
• Submit your web pages i.e. every web page and not just the home page, to the most popular search engines and directory services. Hire someone to do so, if required. Be sure this is a manual submission. Do not engage an automated submission service.
• Keep track of changes in search engine algorithms and processes and accordingly modify your web pages so your search engine ranking remains high. Use online tools and utilities to keep track of how your website is doing.
• Monitor your competitors and the top ranked websites to see what they are doing right in the way of design, navigation, content, keywords, etc.
• Use reports and logs from your web hosting company to see where your traffic is coming from. Analyze your visitor location and their incoming sources whether search engines or links from other sites and the keywords they used to find you.
• Make your customer visit easy and give them plenty of ways to remember you in the form of newsletters, free reports, reduction coupons etc.
• Demonstrate your industry and product or service expertise by writing and submitting articles for your website or for article banks so you are perceived as an expert in your field.
• When selling products online, use simple payment and shipment methods to make your customer’s experience fast and easy.
• When not sure, hire professionals. Though it may seem costly, but it is a lot less expensive than spending your money on a website which no one visits.
• Don’t look at your website as a static brochure. Treat it as a dynamic, ever-changing sales tool and location, just like your real store to which your customers with the same seriousness.

Your website is the hub of your online business; it is the virtual representation of your company whether your company exists physically or not. When you are doing business online, people cannot see you physically like how they could if they were dealing with an offline company. Hence, people do judge you by your covers. This is where a good design comes in.

Imagine if you are running an offline company. Would you allow your salespersons to be dressed in shabby or casual clothes when they are dealing with your customers? By making your staff wear professionally, you are telling your customers that you do care about quality. This works simply because first impressions matter.

Similarly, the same case is with your website. If your website is put together shabbily and looks like a 5 minute “quick fix”, you are literally shouting to your visitors that you are not professional and you do not care for quality.

On the opposite, if you have a totally professional looking website layout, you are giving your visitors the perception that you have given meticulous attention to every detail and you care about professionalism. You are organised, focused and you really mean business.

On the other hand, you should also have anything related to your company well designed. From business cards to letterheads to promotional brochures, every little bit matters. This is because as you grow your business, these items become the face of your business. Once again, think of the “salesperson dressed shabbily” anology, and you will get my point.

A sitemap is often considered redundant in the process of building a website, and that is indeed the fact if you made a sitemap for the sake of having one. By highlighting the importance of having a well constructed sitemap, you will be able to tailor your own sitemap to suit your own needs.

1) Navigation purposes

A sitemap literally acts as a map of your site. If your visitors browses your site and gets lost between the thousands of pages on your site, they can always refer to your sitemap to see where they are, and navigate through your pages with the utmost ease.

2) Conveying your site’s theme

When your visitors load up your sitemap, they will get the gist of your site within a very short amount of time. There is no need to get the “big picture” of your site by reading through each page, and by doing that you will be saving your visitors’ time.

3) Site optimization purposes

When you create a sitemap, you are actually creating a single page which contains links to every single page on your site. Imagine what happens when search engine robots hit this page — they will follow the links on the sitemap and naturally every single page of your site gets indexed by search engines! It is also for this purpose that a link to the sitemap has to be placed prominently on the front page of your website.

4) Organization and relevance

A sitemap enables you to have a complete bird’s eye view of your site structure, and whenever you need to add new content or new sections, you will be able to take the existing hierarchy into consideration just by glancing at the sitemap. As a result, you will have a perfectly organized site with everything sorted according to their relevance.

From the above reasons, it is most important to implement a sitemap for website projects with a considerable size. Through this way, you will be able to keep your website easily accesible and neatly organized for everyone.

Anyone who has been marketing online knows that the lifeblood of a business is the traffic of a site. More visitors equal more sales. However, here are some ways that you can tweak your sites with to improve sales without the need to get more visitors.

The first method is to weave in your personal touch in your sales message. Nobody wants to be sold to by a total stranger, but many people will buy what their close friends recommend to them. If you can convince your audience that you are a personal friend who has their best interest at heart, they will be convinced to buy your products. Remember to speak to an individual in your salesletter, not to your whole audience.

The second method is to publish testimonials and comments from your customers. A good idea would be to publish both good and bad comments; that way prospects will be really convinced that these testimonials are real. When prospects see testimonials on your website, they will have the confidence to buy from you because human beings follow the herd mentality; when others have bought and proven it authentic, they will jump on the bandwagon and buy too.

Use visual representations for the problems and solutions that your product offers. Not everyone will read your text copy from the head to the tail, but most people will pay attention to images on your website.

Offer quality bonuses to accompany the product. When you offer bonuses that complement your product, your prospects will feel it’s a very good deal and it would be stupid to miss it. Be sure to state the monetary value of your bonuses so that people will be even more compelled to grab your good bargain.

Lastly, ask for the sale! Many people entice their prospects with the benefits of their product, sell to them with stories of how it has solved many problems, even offered killer bonuses but forget to ask for the sale. Give a clear instruction on how to buy your product (e.g. “click the button to buy now!”).

Compiling the kernel

Wanted to try out the 2.6 edition kernel? Never knew how to do it? Well heres how! Includes everything from compiling the kernel to configuring your bootloader.

Lets Begin!

cd /usr/src
wget -c http://kernel.org/pub/linux/kernel/v2.6/linux-2.6.7.tar.bz2
tar xvfj linux-2.6.7.tar.bz2
cd linux-2.6.7
make clean && make mrproper
make oldconfig ( or make menuconfig )
make bzImage
make modules
make modules_install

( i prefer this method rather then just “make” )

If you get alot of errors about .ko modules when you run make modules_install you need to update your modutils package with module-init-tools, see below.

Now to copy the files over for the kernel itself.

cp .config /boot/config-2.6.7
cp arch/i386/boot/bzImage /boot/vmlinuz-2.6.7
cp System.map /boot/System.map-2.6.7
mkinitrd /boot/initrd-2.6.7.img 2.6.7

You may experience an error such as this:

/dev/mapper/control: open failed: No such file or directory

if you receive that error run the following commands:

rm -rf /boot/initrd-2.6.7.img
mkinitrd –omit-lvm-modules /boot/initrd-2.6.7.img 2.6.7

Now to add it to the grub / lilo configuration.

[Grub]

Your config will look something like this. Please note you need to follow the format for your current config.

title Red Hat Linux (2.6.7)
root (hd0,0)
kernel /vmlinuz-2.6.7 ro root=LABEL=/
initrd /initrd-2.6.7.img

Add your new entry to the top of the kernel list. Set the default to your working kernel. NOTE: the first kernel in the list is “0″. (ex. default=1)

Now exit. Type “grub” at the bash prompt.

savedefault –default=0 –once

issue that at the grub prompt then use quit to exit. Once your reboot you need to go back in and set the default to the 2.6 kernel by setting default=0

[lilo]

Your config will look something like this. Please note you need to follow the format for your current config.

image=/boot/vmlinuz-2.6.7
label=2.6.7
append=”root=LABEL=/”
read-only
initrd=/boot/initrd-2.6.7.img

Leave the default as is.

/sbin/lilo -v -v
/sbin/lilo -R 2.6.7

Once it reboots and comes back online you can change the default to be 2.6.7 and /sbin/lilo -v -v

The above tells you how to enable failsafe in your kernels. SO that if the box panics the dc tech does not have to console in he just has to reboot the box.

How to install module-init-tools:

cd /usr/src
wget -c http://www.kernel.org/pub/linux/kernel/people/rusty/modules/module-init-tools-3.0.tar.gz
tar -zxvf module-init-tools-3.0.tar.gz
cd module-init-tools-3.0
./configure –prefix=”"
make moveold
make install
./generate-modprobe.conf /etc/modprobe.conf

How to determine what boot loader you are using?

dd if=/dev/hda bs=512 count=1 2>&1 | grep GRUB
dd if=/dev/hda bs=512 count=1 2>&1 | grep LILO

one of them will kick back something like:

root@w00t [~]# dd if=/dev/hda bs=512 count=1 2>&1 | grep GRUB
Binary file (standard input) matches
root@w00t [~]#

which means its using grub.

Rkhunter is a very useful tool that is used to check for trojans, rootkits, and other security problems. This tutorial will touch on installing and setting up a daily report for rkhunter.

Update Aug. 23, 2005

Installing:

wget http://downloads.rootkit.nl/rkhunter-1.2.7.tar.gz
tar -zxvf rkhunter-1.2.7.tar.gz
cd rkhunter-1.2.7
./installer.sh

Now you can run a test scan with the following command:

/usr/local/bin/rkhunter -c

How to setup a daily scan report?

pico /etc/cron.daily/rkhunter.sh

add the following replacing your email address:

#!/bin/bash
(/usr/local/bin/rkhunter -c –cronjob 2>&1 | mail -s “Daily Rkhunter Scan Report” email@domain.com)

chmod +x /etc/cron.daily/rkhunter.sh

Updating rkhunter
gets the latest database updates from their central server and matches your OS better to prevent false positives.

rkhunter –update

I just got a false positive!! What do i do?

False positives are warnings which indicates there is a problem, but aren’t really a problem. Example: some Linux distro updated a few common used binaries like `ls` and `ps`. You (as a good sysadmin) update the new packages and run (ofcourse) daily Rootkit Hunter. Rootkit Hunter isn’t yet aware of these new files and while scanning it resports some “bad” files. In this case we have a false positive. You could always have your datacenter or a system administrator check out the server to verify that it is not compromised.

More information on rkhunter can be found here: http://www.rootkit.nl

Telnet sends clear text passwords and usernames through logins and should be disabled on all web servers and replaced with SSH.
Some hosting providers are not disabling telnet by default but you should ensure that it has been turned off as it’s a great security risk to your servers. TELNET server listens for incoming messages on port 23, and sends outgoing messages to port 23.

1. Login to your server through SSH and su to root.

2. Type pico /etc/xinetd.d/telnet

3. Look for the line: disable = no and replace with disable = yes

4. Now restart the inetd service: /etc/rc.d/init.d/xinetd restart

5. Turn off it through chkconfig as well because it can still start through that.
/sbin/chkconfig telnet off

6. Scan your server to ensure port 23 is closed.
nmap -sT -O localhost
Also run ps -aux | grep telnet and if you find anything other than “grep telnet” as result kill the process.
