By now, most bloggers have heard
announcement that
Big 3 search engines - Google, Yahoo, and MSN - have united in support of a new tag that will supposedly combat comment spam. The new tag is a nofollow attribute that can be added to links. When added to links in comment tags,
search engines will ignore them.An excellent discussion of this new tag and how it works can be found at Danny Sullivan's Search Engine Watch: http://blog.searchenginewatch.com/blog/050118-204728
Google announced
new tag in a 1/18/2005 post to their own blog: http://www.google.com/googleblog/
And Microsoft added their support to
new tag in this post: http://blogs.msdn.com/msnsearch/archive/2005/01/18/nofollow_tags.aspx
At first blush, anything that can help cut down
comment spam that most bloggers are daily subjected to would seem to be a good thing. It can be pretty upsetting to access your blog in
morning and find 50 junk comments with links to casino, adult, and pharmacy sites. If your blog has any PageRank, you can expect to find more of this garbage polluting your site every day. Fighting
spread of comment spam has become a necessity.
But after first cheering
proactiveness of
search engines, many bloggers have stepped back and taken a closer look and they don't like what they see. You can read a sampling of their thoughts at Search Engine Watch Forum: http://forums.searchenginewatch.com/showthread.php?t=3797
Brian Turner's incisive article "New Nofollow Tag Cheers Bloggers but Fails Blogs" discusses some of
potential abuses of
new nofollow tag: http://www.platinax.co.uk/news/archives/2005/01/new_nofollow_ta.html
And Jim Pryke's article "Bloggers Cheer Google As Their Search Rankings Plummet" makes it very clear that not only will this NOT stop comment spam. But it will actually hurt bloggers as a community: http://netinstitute.com/archives/2005/01/20/bloggers-cheer-google-as-their-search-rankings-plummet

new tag and how it will get abused, be sure to take a look at Link Condom: http://www.linkcondom.com
I have to agree with these bloggers that
nofollow tag won't even put a dent in
problem of comment spam. You have to realize that
comment spammers who cause
most problems are
ones who use automated bots to spread their spam onto every blog they find. The fact that they find a blog using
nofollow tag won't stop
bot from posting. If you have a popular blog, you'll still wake up every morning to find 50 casino/pharmacy/adult ads on your blog. You'll still have to spend
time deleting those posts to clean up your blog.
You see,
problem to bloggers isn't that those comment links pass PR. It's
fact that those spam posts make your blog look like garbage. Whether
links pass PR or not isn't
big issue for bloggers. It's
time it takes to get rid of unwanted comments and
detraction to their sites. The nofollow tag won't do a thing about that problem. You'll still have
problems, even if you use
tag.
Think about this: how effective have email filters been in stopping email spam? As most of us know, they've hardly done any good at all. Email spam becomes a bigger problem every day. Spammers really don't care if some of their emails are blocked. They just send more of it to compensate. The same will be true of
automated comment spam bots.
The fact of
matter is, there are already much better tools in most blogging software to fight comment spam AND save
time and effort of
blogger at
same time. There are already a number of plugins for WordPress, Moveable Type, and other blogs. There will undoubtedly be more in
future. These tools are already more effective at fighting comment spam than this nofollow tag will ever be.
What is unfortunate is that
people
nofollow tag will really hurt is bloggers themselves. Traditionally, bloggers have read and commented in each other's blogs. And these comments have added value. When I write an article for my blog, I love it when other bloggers take
time to add their insights on
topic I'm discussing. These comments add content to my site and continue
discussion. This is one of
reasons blogs are so easy to grow into topic-specific information-rich sites that are popular with readers. Unlike static sites, they offer two-way communication between reader and blogger. They become communities.
