Before we do that though, it's important to understand that if you want local services then it always counts to have an agency in your local city. For example, if you are in seeking a Hong Kong SEO Company then you'd be wise to use directories and other similar resources. The same thing goes for New York or London.
Realistic Offers - If something seems too good to be true, it most often is. Look for firms that provide practical outcomes rather than promises. SEO is a continuous process, and no one can guarantee ranks 100 percent because search engines are outside an agency's control. Any guarantees of rankings in a matter of hours or days should raise an instant red flag.
Experience — Take a look at how long the firm has been in operation. The amount of time that a firm has been in operation reflects its level of expertise. Companies that have worked with a large number of clients have expertise in a variety of sectors and understand what works and what doesn't.
SEO Case studies — A good SEO firm should not only have case studies available but should also be willing to show you them. The case studies should highlight their accomplishments and provide specific instances of their work, demonstrating their knowledge and ability. Case studies are proof of a company's capacity to provide excellent outcomes, so be sure the organizations you're considering can offer you with them.
SEO or SEM Certifications - While there is no such thing as an ‘SEO certification,' many genuine businesses have standard certifications in Analytics and PPC. Google, Yahoo, and Bing each have their own PPC certificates, and organizations that have earned them have demonstrated their understanding of each search engine's advertising systems.
Ethical business practices Before talking to your agency, be sure to ask them to describe any tactics they employ and have them describe it to you in the language you can comprehend. If anything seems manipulative or immoral, it should immediately raise red flags. Caring organizations will be able to communicate the intricacies of their strategy and procedures so that customers have no reservations about their methods.
