Flash to load. Search has become such an effective advertising medium in large
part because of its simplicity.
I strongly urge not using Flash on most websites because it gives search engines
inadequate content to read. If you do not give search engines much text, then you
will need a larger linking campaign to get that page to rank well. If you do embed a
Flash object, make sure you include HTML content in the page, and either use
Flash Object for Flash detection or provide content inside noembed tags to help
search engines understand what is inside the flash.
Session IDs & Do Not Feed Search Engines Cookies
Assuming you have many quality incoming links and your site is still not indexed
after an extended period of time, you should evaluate the crawlability of your site.
If you have not received a spam penalty and your site was not previously banned,
you may have technical issues.
There are many dynamic websites that only get a fraction of their web pages
indexed. Search engines are getting better at finding and crawling dynamic pages,
but they still do not like cookies or session ids. Search engines will not accept a
cookie, and if a search engine thinks you are giving it a session ID number, it will
not want to cache your pages (and if they do you will run into duplicate content
issues
.
If search engines indexed sites that gave them session ID numbers, they could
draw too much from the site in a quick amount of time and crash the server, they
could get the idea that the site is much larger than it actually is, or they could fill
their index up with pages that no longer exist. If you have a shopping cart, do not
issue a session ID until an item is placed in the cart.
Dynamic Site Fiction
Some ill-informed people say that search engines penalize sites for having a .asp or
.php extension. This is complete garbage.
Search engines read any page as hypertext no matter what the file extension is. If a
site is not getting indexed, it usually is lacking in sufficient inbound link popularity,
is using JavaScript or other client-side navigation that spiders may not follow, has
complex URLs with too many variables, has many dead URLs, has duplicate
content issues, or is issuing the search engine spiders a session ID or cookies.
Is My Site Cached?
To check whether or not your page is in the Google cache, you can do a search in
Google for ?cache:www.mysite.com/mypage.whatever.? If the page is in their
cache, then Google is reading it just fine.
