One of the most common BHSEO strategies is to purchase a bulk batch of domain names and redirect customers to the original website using a 301 redirect or 302 redirect function. The Uniform Resource Locator ('URL') address is often changed or permanently moved from one page to another page while a website is migrated or updated. Redirects are then required to reach to a new page or new URL address. Technically, it is called a "Sever-side Redirect". A 404 error often occurs as a result of broken links, which can seriously harm a website's ranking. A 404 error will not only have a negative impact on web users, but also on web spiders since 404 error pages degrade the performance of a web spider. To solve this issue, a 301 redirect is used. BHSEO experts intentionally purchase domain names with typographical errors. These become relevant when a web user accidentally inputs an incorrect website address into the search box on a search engine site. When this occurs, the user is hijacked and forced to visit the targeting website. This is known as "typosquatting" or URL hijacking which is a form of cybersquatting.
In the USA, "cybersquatting" is regulated under the Anticybersquatting Consumer Protection Act ('ACPA') which was enacted in 1999. This Act specifically targets cybersquatters who purchase and register domain names although they do not have any intention of using them. Unlike the USA, there is no direct legislation, which regulates cybersquatting in Australia. Instead, the conduct of falsely suggesting a connection between a registrant and their business is potentially caught by section 18 of the ACL in Queensland. Section 18 states that a person must not, in trade or commerce, engage in conduct that is misleading or deceptive or is likely to mislead or deceive.
The issue of “in trade and commerce” is well described in Concrete Constructions (NSW) Pty Ltd v Nelson (‘Concrete Case’). The respondent (‘worker’) was employed by the appellant corporation (‘the company’). He was injured after falling down an air conditioning shaft while attempting to remove a grate. He was told by the foreman that the grate was secured by three bolts so that it was safe to remove. He brought proceedings against the company for the breach of section 52 of the Trade Practices Act 1974 (Cth) ('TPA'). The court ruled that foreman’s conduct was not conduct in trade or commerce under section 52 of the TPA and allowed appeal. The majority chose narrower interpretation of ‘in trade and commerce’. Under the narrow interpretation, ‘in trade and commerce’ is a conduct which is itself an aspect or element of activities or transactions which, of their nature, bear a trading or commercial character. Unlike Concrete Case, SEO companies which provide BHSEO service to Australian consumers will be captured under section 18. Also, the term, 'trade or commerce', is defined in section 2(2) in the ACL, and states that the conduct of the business must be in trade or commerce within Australia or trade or commerce between Australia and a place outside. This is quite broad and thus will catch all SEO’s working in Australia or with an Australian consumer.
To be caught under section 18, the conduct must also be misleading or deceptive or likely to mislead or deceive. In Parkdale Custom Built Furniture P/L v Puxu P/L, the court adopted an objective approach to determine whether the public at large was likely to be misled. Chief Justice Gibbs stated that the relevant person who may be misled is the reasonable member of the class directly affected by misleading or deceptive conduct. Here, if an article was properly labelled and displayed the name of the manufacturer, ordinary reasonable member of the public would not be misled: Collins Marrickville Pty Ltd v Henjo Investments Pty Ltd & Ors.
