Search engines have also reached out to the
SEO industry, and are frequent sponsors and
guests at SEO conferences, chats, and
seminars. In fact, with the advent of paid
inclusion, some search engines now have a
vested interest in the health of the
optimization community. Major search engines
provide information and guidelines to help
with site optimization.Google has a Sitemaps
program to help webmasters learn if Google
is having any problems indexing their
website and also provides data on Google
traffic to the website. |

The
leading search engines, Google, Yahoo!
and Microsoft, use crawlers to find
pages for their algorithmic search
results. Pages that are linked from
other search engine indexed pages do not
need to be submitted because they are
found automatically. Some search
engines, notably Yahoo!, operate a paid
submission service that guarantee
crawling for either a set fee or cost
per click. Such programs usually
guarantee inclusion in the database, but
do not guarantee specific ranking within
the search results. Yahoo's paid
inclusion program has drawn criticism
from advertisers and competitors. Two
major directories, the Yahoo Directory
and the Open Directory Project both
require manual submission and human
editorial review. Google offers Google
Webmaster Tools, for which an XML
Sitemap feed can be created and
submitted for free to ensure that all
pages are found, especially pages that
aren't discoverable by automatically
following links. |
