This is a short informative post for all those who share Download files
or any other web related resources with there readers. A PageRank by
Google is an important rank that determines the importance of your
website or blog in the eyes of search engine spiders. A spider is a
robot that is responsible for crawling your content and indexing it on
data bases. Since the entire infrastructure of GOOGLE PR is based on
quality backlinks therefore it very important that you should flow the PR juice
wisely and do not waste it on useless links. By useless links I mean
websites that use login structures or IFrames. An I framed webpage is
not crawled by spiders because it can not access it. All social media
networks have a login algorithm that allows visitors only with a unique
password. When you link Facebook Profiles, Twitter or Blogger Profiles
or any other social network, make sure you add the nofollow tag to them.
Further you must also add a nofollow tag
to the links in your table of contents. If you write tutorials like me
and share a DEMO link or Download Link then make sure you tag them as
nofollow because linking files and hosting websites will drink all your
PR juice and will slow down your PR progress on next PR update.
There is also a noindex tag which should be added only when you feel that even the text of the link is not important.
How to add Nofollow Tag in HyperLinks
A link has this HTML code,
<a href="http:xyz.com">Download</a>
To make any link nofollow just change the link in this way,
<a rel="nofollow" href="http:xyz.com">Download</a>
To add a noindex tag which is not very necessary do this,
<a rel="noindex" rel="nofollow" href="http:xyz.com">Live DEMO</a>
now your PR is more healthy and safe.
What links should be kept dofollow
UPDATE: A detailed post has been written please read: When should you nofollow links?
Always make it a habit of linking well established websites and
services. If you are sharing a Facebook Plugin then feel free to link
the developers page else if you are sharing a news on AdSense then you
must link to the AdSense blog and openly mention things that matter with
relevant source links. This will increase your BLOG reputation in the
eyes of robots and will help you you rank higher. Blogs become
authorities by linking relevant stuff and avoiding useless iframed
pages.
Even I have done the plunder of linking demo and download links a lot
but the better you know the good it is. I hope this little info may help
you preserve and protect your newly gifted PRs and may help you to
utilize it wisely. Wish you all the best.
