Ranking Rules Of
Thumb
The simple rule of thumb is
that content counts, and that content near the top of a page
counts for more than content at the end. In particular, the
HTML title and the first couple lines of text are the most
important part of your pages.
If the words and phrases that
match a query happen to appear in the HTML title or first
couple lines of text of one of your pages, chances are very
good that that page will appear high in the list of search
results.
A crawler/spider search engine
can base its ranking on both static factors (a computation of
the value of page independent of any particular query) and
query-dependent factors.
Values
- Long pages, which are
rich in meaningful text (not randomly generated letters and
words).
- Pages that serve as good
hubs, with lots of links to pages that that have related
content (topic similarity, rather than random meaningless
links, such as those generated by link exchange programs or
intended to generate a false impression of
"popularity").
- The connectivity of
pages, including not just how many links there are to a
page but where the links come from: the number of distinct
domains and the "quality" ranking of those particular
sites. This is calculated for the site and also for
individual pages. A site or a page is "good" if many pages
at many different sites point to it, and especially if many
"good" sites point to it.
- The level of the
directory in which the page is found. Higher is considered
more important. If a page is buried too deep, the crawler
simply won't go that far and will never find
it.
- These static factors are
recomputed about once a week, and new good pages slowly
percolate upward in the rankings. Note that there are
advantages to having a simple address and sticking to it,
so others can build links to it, and so you know that it's
in the index
- Query-Dependent
Factors
- Query words and phrases
appearing early in a page rather than late.
- Meta tags, which are
treated as ordinary words in the text, but like words that
appear early in the text (unless the meta tags are patently
unrelated to the content on the page itself, in which case
the page will be penalized)
- Words mentioned in the
"anchor" text associated with hyperlinks to your pages. (E.g., if
lots of good sites link to your site with anchor text
"breast cancer" and the query is "breast cancer," chances
are good that you will appear high in the list of
matches.)
Blanket Policy On
Doorway Pages And Cloaking
Many search engines are
opposed to doorway pages and cloaking. They consider doorway
and cloaked pages to be spam and encourage people to use other
avenues to increase the relevancy of their pages. We’ll talk
about doorway pages and cloaking a bit later.
Meta Tags (Ask.Com As An
Example)
Though Meta tags are indexed
and considered to be regular text, Ask.com claims it doesn't
give them priority over HTML titles and other text. Though you
should use meta tags in all your pages, some webmasters claim
their doorway pages for Ask.com rank better when they don't use
them. If you do use Meta tags, make your description tag no
more than 150 characters and your keywords tag no more than
1,024 characters long.
