If the title ever gives you a hint of possibly being able to escape the consequences of unethical targeted web traffic techniques, make that: “that will get you banned”. Black Hat SEO is too risky of a process (and, well, I just clearly said unethical) to getting targeted traffic to your site.
But there may be some amateurs out there whose knowledge of search engine optimization is still unripe and may unknowingly commit these mistakes. So here are some of the techniques that can get you banned when you are only doing your best to rise on top of search engines.
Meta Tag Stuffing. Meta tags play a great role in making your website search engine optimized. When your meta tag contains keywords or key phrases that are specifically targeted by certain website surfers, then you have an advantage (of course this is not all that there is for being website visible).
Meta tags are not visible to web viewers. However, its use is highly important in giving directions to search engines whenever a search is performed (i.e. they classify your website as relevant to a search if, partially, your site’s meta tags contain the search words). Abuse of meta tags happen when they are being stuffed with keywords all for the sake of SEO, instead of featuring quality content that realistically describes what the web page is about. So be careful not to overstuff your meta tags with keywords. Quality should always be first.
Alt Image Tag Stuffing. This is similar to meta tag stuffing, only that the practice is being done to the alt image tags. All images on a web page can have alt tag counterparts. If your computer can view the images, you will likely not see them except if you hover over the images or try to copy the entire website content and paste them, say, on a Word or Notepad document (and of course if you view the page source).
Alt tags also replace the images whenever a website reader’s computer is not able to load the website graphic. Alt tags are abused whenever they are stuffed with keywords that are not really appropriate to describe the images – but which are used just so the search engine crawlers recognize the availability of the words on your pages (which partially reflects on the relevance of your page to a search). So you might get targeted traffic because of the presence of specific keywords on your page, but then your website quality may not really deserve it.
Title Tag Stuffing. This is also similar to the first two unethical techniques mentioned above. The title of your website should reflect only what your website is really about. The title serves as your website identity. If you fake it through keywords that have nothing to do with your website content, if you make the keywords repetitive that the message makes almost no real sense, then it certainly is considered as black hat technique.
You should never get targeted web traffic through the ways mentioned above. The grave consequences will harshly affect you in the long run, for a long period.
