do search engines spider the "alt"
text in images?
- In most cases, no
- However, Google and Lycos do
- Don't gratuitously put in keywords into the "alt"
tag
- The alt text has to describe the image so it
still makes sense to users who have graphics switched
off in their browser
- Directories will penalise if not

can a search engine follow the links in an image map?
- Sometimes - don't rely on it though
- Provide hyper links and navigation
in an alternative format as well
what about Flash animation?
- Search engines can't spider Flash sites at the
moment
- Directories will also penalise the use of Flash
if it takes too long to download
- Yahoo won't list Flash only sites
- Try putting just parts of the site in Flash
- Don't use a browser plug-in re-direct - provide a button
for the user to choose the html or flash version
of your site
- Good usability
- Re-directs are often considered spam
by search engines
- Can check your site stats for percentage of
users choosing which version
- Scrap the Flash version if people aren't choosing
it

does it matter how long it takes
for a page to download?
- Yes
- Figures from Yahoo and LookSmart state within
8 seconds on a 28kbps modem
back to top
does the actual design effect chances
of getting listed?
- Maybe
- The over use of graphics can have a detrimental
effect on download time (see above)
- Text rich sites get listed more highly than
graphic heavy
- Simply because the search engine can index text
and links
- Using JavaScript can prevent the search
engine spidering the site
- Put it in a separate file
- Using layers which contain links / content
can prevent this content getting indexed
- The site needs to be:
- Readable (no small fonts)
- Have intuitive navigation
- Consistent in layout and design
- Quick to download
- Information should be "above the fold"
- i.e. near the top of the page
back to top
are frames really bad for search engine
listings?
- Mostly yes
- Search engines can't spider a frameset
- Even if you successfully manage to get listed, the spider
will eventually return to the site and index pages
such as the navigation frame on its own
- Even if your pages get listed, the search engine won't
always put the frameset back together correctly
- Looks unprofessional
- Is useless to a user if they click on a single page
out of the frameset from the list of sites a search
engine displays
- Getting rid of frames always improves ranking
- If you really have to use frames, use
the <noframes> tag properly
back to top
are splash pages really bad for
listings?
- Yes
- The home page may be the only page indexed and
often ranks higher than other pages
- Some search engines and directories won't list site
if it has a splash entry page (e.g. Northern Light)
back to top
what about dynamically
generated pages (i.e. from databases)?
- Search engines can't spider urls with special characters
in them (? % = " etc)
- Test your pages by removing everything after the special
character, if the page still displays - OK for search
engines
back to top
what about doorway pages?
- These are pages created specifically for each search
engine spider, based on what is known about that spider
- Often keyword heavy
- Require an extra click from the user
- Can be considered spam
