These are considered the worst Black hat Seo practices :
Keyword stuffing: Packing long lists of keywords and nothing else onto your site will get you penalized eventually by search engines. Learn how to find and place keywords and phrases the right way on your Web site.
Invisible text: This is putting lists of keywords in white text on a white background in hopes of attracting more search engine spiders. Again, not a good way to attract searchers or search engine crawlers.
Doorway Pages: A doorway page is basically a “fake” page that the user will never see. It is purely for search engine spiders, and attempts to trick them into indexing the site higher. Read more about doorway pages.
If you use automatic traffic exchanges where users sit in front of a web browser on a PC and watch random websites load, you would get banned from revenue sharing services like Adsense, Adbrite, and Pay per Impression, and Paid per click ads since you need to use natural traffic from people who found your links on other websites, adwords, adbrite, yahoo ads to earn money with ads.
Automatic traffic exchanges are also not very useful, and can slow down your website for people who are interested in your site. Plus, your web host might complain you are using too much bandwidth.
The only type of traffic exchange which is useful for a forum or blog is post exchanges or guest posting since you get topics and replies out of your exchanges which can increase search traffic if the topics and replys are good or become viral.
A few Dofollow comments would be fine, but if you post thousands with comment posting software, or bots then it is not recommended.
I'm not sure that mass dofollow comment posting is a good for SEO.
If you write too many dofollow comments, search engines may think you are spamming, and the webmaster of the blog might not appreciate you posting a lot of comments for the sake of getting backlinks instead of posting something useful to add to the conversation, and people can report you to Google and other engines if you think comment spamming.
I think you're talking of sites where you earn credits by visiting others' sites and then people visit your site. No, it's not a BH SEO practice, since there's no 'SEO' involved per se.
Traffic exchanges are good for stat inflation, eg page views, UV's etc.
Isn't Google Adwords, Yahoo Ads, etc considered Traffic Exchanges where you exchange money for visitors who click on your ads?
I heard using web bots to get traffic can get you in trouble with your web host since if there are too many bots visiting your website the web host web server will shut down your site for slowing down their server.
No. Google Adwords, Yahoo Ads are not traffic exchanges, but PPC advertising companies. You pay there for listing, and not traffic. That's the difference.
And your host will complain only if you use too many resources of the host and/or cause trouble to other sites.
Are Traffic Exchanges' visitors in most cases not real human, but web bots?
If they are bots wouldn't the web host think your site is being DDoS, or attack since it looks kind of suspicious, and just block traffic from certain IP. domain ranges?
Traffic Exchanges are a simple concept of online advertising where members exchange traffic. Basically, you view my ads, I view yours, to make sales, build opt-in list, and branding.
Generally, one surfs a traffic exchange for credits by viewing member sites, and those credits are assigned to your sites to be viewed by others. In addition, traffic exchanges offer varying exchange ratios, membership upgrades, prizes, and referral rewards, mostly a percentage of traffic they earn, and common, commissions too.
You won't find many real traffic exchange sites. Many sites/users use bots to get give others views and get more views for their sites. Best way to do this is contact directly with other sites and make a deal.
PPC ,CPM networks like AdSense do not like this practice at all. They wouldn't bad anyone if they get caught.
Traffic exchanges mean that you are trying to boost your stats or in someway make it look like you are getting more traffic than you are really getting. No matter why you are doing it, it is probably not for a good reason. Perhaps you are trying to get more people to pay for advertisements on your site, I don't know. But for those of you that need to make sure someone doesn't just have inflated traffic exchange stats, you can just look at the bounce rate on their analytics. Just have them screen shot it for you. If the bounce rate averages close to what the traffic exchange site does, then you might have an issue. Usually that is a good indicator of where their traffic comes from.
Google forbids the use of traffic exchanges for sites using their Adsense. So even if it's not Blackhat, you could still be messing up your earnings potential by cheating on traffic.
My opinion is Traffic Exchange is BHSeo because it has bad affect on bounce rate and search engines detect the TEXCH sites so its not good technique for SEO.
