How
Do Search Engines Work - Web Crawlers from Laptop Repair Data
It is the search engines that finally bring
your website to the notice of the prospective customers. Hence it is better to
know how these search engines actually work and how they present information to
the customer initiating a search.
There are basically two types of search
engines. The first is by robots called crawlers or spiders.
Search
Engines use
spiders to index websites. When you submit your website pages to a search
engine by completing their required submission page, the search engine spider
will index your entire site. A ‘spider’ is an automated program that is run by
the search engine system. Spider visits a web site, read the content on the
actual site, the site's Meta tags and also
follow the links that the site connects. The spider then returns all that
information back to a central depository, where the data is indexed. It will
visit each link you have on your website and index those sites as well. Some
spiders will only index a certain number of pages on your site, so don’t create
a site with 500 pages!
The
spider will periodically return to the sites to check for any information that
has changed. The frequency with which this happens is determined by the
moderators of the search engine.
A
spider is almost like a book where it contains the table of contents, the
actual content and the links and references for all the websites it finds
during its search, and it may index up to a million pages a day.
Example: Excite, Lycos, AltaVista and Google.
When
you ask a search engine to locate information, it is actually searching through
the index which it has created and not actually searching the Web. Different
search engines produce different rankings because not every search engine uses
the same algorithm to search through the indices.
One
of the things that a search engine algorithm scans for is the frequency and
location of keywords on a web page, but it can also detect artificial keyword
stuffing or spamdexing. Then the algorithms analyze the way that
pages link to other pages in the Web. By checking how pages link to each other,
an engine can both determine what a page is about, if the keywords of the
linked pages are similar to the keywords on the original page.
Keyword Density
Keyword
density is an indicator of the number of times the selected keyword appears in
the web page. But mind you, keywords shouldn’t be over used, but should be just
sufficient enough to appear at important places.
If you repeat your keywords with
every other word on every line, then your site will probably be rejected as an
artificial site or spam site.
Keyword density is always expressed as a percentage
of the total word content on a given web page.
Suppose you have 100 words on your webpage (not
including HMTL code used for writing the web page), and you use a certain
keyword for five times in the content. The keyword density on that page is got
by simply dividing the total number of keywords, by the total number of words
that appear on your web page. So here it is 5 divided by 100 = .05. Because
keyword density is a percentage of the total word count on the page, multiply
the above by 100, that is 0.05 x 100 = 5%
The accepted standard for a keyword density is
between 3% and 5%, to get recognized by the search engines and you should never
exceed it.
Remember, that this rule applies to every page on
your site. It also applies to not just to one keyword but also a set of
keywords that relates to a different product or service. The keyword density
should always be between 3% and 5%.
Simple steps to check the density:
- Copy and paste the content from an individual web page into a word-processing software program like Word or Word Perfect.
- Go to the ‘Edit’ menu and click ‘Select All’. Now go to the ‘Tools’ menu and select ‘Word Count’. Write down the total number of words in the page.
- Now select the ‘Find’ function on the ‘Edit’ menu. Go to the ‘Replace’ tab and type in the keyword you want to find. ‘Replace’ that word with the same word, so you don’t change the text.
- When you complete the replace function, the system will provide a count of the words you replaced. That gives the number of times you have used the keyword in that page.
- Using the total word count for the page and the total number of keywords you can now calculate the keyword density.
Must Have Features Your Web Site
Just don’t focus on the home page, keywords and titles.
The first step to sales when customers visit your site to see the
products they were looking for. Of course, search engine optimization and
better rankings can’t keep your customer on your site or make them buy. The
customer having visited your site, now ensure that he gets interested in your
products or services and stays around. Motivate him to buy the product by
providing clear and unambiguous information. Thus if you happen to sell more
than one product or service, provide all necessary information about this, may
be by keeping the information at a different
page. By providing suitable and easily visible links, the customer can navigate
to these pages and get the details.
Understanding Your Target Customer
If you design a website you think will attract clients, but you
don’t really know who your customers are and what they want to buy, it is
unlikely you make much money. Website business is an extension or replacement
for a standard storefront. You can send email to your existing clients and ask
them to complete a survey or even while they are browsing on your website. Ask
them about their choices. Why do they like your products? Do you discount
prices or offer coupons? Are your prices consistently lower than others? Is
your shipping price cheaper? Do you respond faster to client questions? Are
your product descriptions better? Your return policies and guarantees better
than your competitor’s? To know your customer you can check credit card records
or ask your customer to complete a simple contact form with name, address, age,
gender, etc. when they purchase a product.
Does your website give enough contact information?
When you sell from a website, your customer can buy your products
24 hrs a day and also your customers may be from other states that are
thousands of miles away. Always
provide contact information, preferably on every page of your website, complete
with mailing address, telephone number and an email address that reaches you.
People may need to contact you about sales, general information or technical
problems on your site. Also have your email forwarded to another email address
if you do not check your website mailbox often. When customer wants to buy
online provide enough options like credit card, PayPal or other online payment
service.
