Inter-Page or Site-Wide Considerations
Consider how your pages link together
Often relevancy can be inferred from what the text of a link says about
the page that it is linking to. Therefore, it goes without saying
that it may be better to use actual text links rather than images
(if you have to use an image ensure your ALT tag is complete).
You
may benefit if the link's text contains the keywords that are present on
the target page... However, especially with Google and their so-called
'Over Optimisation Penalty' you may be well advised to NOT match
the link text to the page's keywords with the exact keyword phrase.
You
can have keywords/synonyms in the link text - just not the exact same
keyword phrase as appears in the target page. This is because it seem that
most of the pages that where targeted for 'demotion' in Google's last
shake up seemed to be relying too much on this strategy.
With
a similar care, take a look at the other elements that make up a link's
URL. Keywords can be judiciously incorporated into the directory structure
as directory names.
You
may also wish to consider the use of appropriate sub-domains that take the
form keyword.mywebsite.com
for example... though of course you can't expect it to as much weight as
the primary domain name.
Ensure that all your pages can be found
Since searching spiders are quite interested in finding content (which
they can then index and from which they can also work out how relevant or
important your page should be) - it's important to make sure that the
spider/robot can crawl your pages without too much trouble.
To
help the indexing 'spider' get all the relevant content from your site, it
can be helpful to run some software to check for broken links. Sometimes
if a search engine spider comes across a broken link it may just give up
on that particular page.
Site Maps - Another way of ensuring that all your important
pages are found is by constructing a single page that links through to
every other page on your site.
Make
sure that this site map page can then be found easily by putting it on
your home page/index page (perhaps nearer the top). That way, when the
spider comes-a-crawling it can find this 'site map' page and therefore
discover all the other pages on the site with relative ease.
Stopping certain pages from being Spidered
Sometimes you may have your reasons for not wanting a page to be spidered.
For
example, you may have part of your website that is licensed from another
site (therefore have identical pages), which you don't want the spider to
index because they might possibly chuck out your whole domain because they
think your only a 'duplicate site'.
Or
perhaps more commonly, you may have some complex, script based dynamic
pages that you simply don't want a spider entering into and 'clicking' on
links. For example, if you're trying to conduct some kind of online poll
of survey, perhaps.
Another reason is if you have personal or more private information which
you don't want to be too easily
You
can use a robots.txt
file to control which parts of the site the spider/robot should stay away
from.
