What is a spam comment?

which is not related to your topic use spam buster.

Why sky is blue? Why earth is round? Why i am on this forum?If you are here, then probably you are here to ask some specific questions on SEO if not very specific. If you can't do basic search on Google, then how you will do SEO i wonder.

Well the sky is blue to due to the refractive index of Ozone.
The earth is round due to the attractive forces of gravity (actually its not a perfect sphere)

but what the poster wants to look at (after a Google search of course) is the rel=nofollow attribute on a link.

Eg



Adding in the nofollow part makes it useless for SEO purposes and as such it will get spammed a lot less.

Another option you can take is to manually verify all posts.

You can run a script that has certain stop words suchs as "poker" or "free casion" for example. That will sort out a lot of it.

You are wrong here. Its time to put the record straight.How search engines treat the nofollow:

Google- doesn't follow the nofollow link and consequently doesn't crawl/index the linked page. Nor it passes any trust and attribution (passing PR, link authority) to the linked page.

Yahoo and MSN- follow the nofollow link and crawl/index the linked page.They even counts the nofollow links as backlinks but doesn't not pass any trust and attribution to the linked page.

Ask-follows the nofollow link and crawl/index the linked page and also pass any trust and attribution to the linked page.


Above all, the nofollow links can't stop the traffic coming to your website. So nofollow links are not useless for seo purpose.

Spammers try to use your blog in order to link to their website for SEO purposes

So when you see a link in your blog check it out or simply put the attribute "nofollow"

I guess thats a perspective thing.

No ammount of NOFOLLOW links will make your site rank higher, thats fact so from that perspective it is useless for SEO purposes so my comment is correct.

On the other hand having lots of traffic that might link to your site and help to sway user behaviour factors may have an indirect effect on SERPs and thus could be considered benneficial to SEO.

IMO getting a nofollow link is not considered SEO, its just considered online marketing. But again, thats a perspective thing. Depending on whether we are talking about Direct of Indirect SEO effects I am either correct or correct to a point.

It will in case of Ask and other search engines who completely ignore nofollow. Even if you ignore any advantage of nofollow links ranking wise, it can still get your page crawled and indexed in yahoo and MSN. So how it can be useless for SEO purpose. What you learned from my post anyways?




Yes you are the best

And from my perspective:

1. No follow does brings in traffic, there's never a doubt about that.

2. Even though Ask.com neglects the nofollow tag completely, yet how much market share does it have? Hardly 10-15 -20%? How much could you gather from that? A handful of dust.. may be?

3. The best to look at this is, even though the link is nofollowed, the comment, the actual comment content is still there for the search engines to read and give what so ever desired benefit. thats perfectly justified, you will get the content weight..but not the links juice that can actually impact your SERPS big time..

4. There will be NO.. yea u read that right.. NO benefit with the SERPS in any of the major engines G,Y,M that hold the majority of market share and can actually impact conversions. And since, you are not getting a Dime out of it, why bother to touch the rattling snake? Just say your words and make your presence felt with them, not with your URL..!

5. Had those no follow thingies impacted the ranks, Wikipedia, answers.yahoo.com, techno etc would have been in a living hell at present..

6. No-Follow is best suited to stop users from gaining that little yet extra Link Juice from your webpage that might impact there SERPS.. Perhaps, in general they are useless for SEO Purpose, But Good for SEM/Online Marketing/Internet Marketing Purpose.. No? Follow?

Also, important thing is, No-Follow does not stops spamming, it just sucks the spam poison from your webpage..! and disable the LJ..

In the end, Both of you are right on your points, yet it all boils down to way we see the world - Perspective, is the word!!

For stop spamming I think we will get support some software for stop abusing it may effect in some extent but can't stop completely for this we will have check our control panel time to time we will have to remove spamming manually.....

I think the point is being missed here.

Surely most spam is performed by bots, not humans. To a bot, whether the NOFOLLOW is added after a post is irrelevant, isn't it? If it is is crawling the net looking for blogs to spam, does it care if some of them get edited afterwards? Writing code to check for this happening is more complicated than just spamming indiscriminately.
