(d) Ask them if they use any of black hat SEO strategies. If you are not getting any answers or if you get untruthful answers by denying that they do use black hat strategies, try asking all their optimizing strategies. This process requires enough knowledge about black hat SEO strategies. Cross-examining them would not be possible if you, as the cross-examiner, have not familiarized the black hat SEO tricks.

(e) Also, ask about where they get their backlinks. Check the sites where backlinks are coming from if they are reputable sites or mere link farms. Your site must not be linked from link farms or else, your site ranking would eventually get buried in the listing or get banned for worse.

(f) Meet with the representatives of your prospect SEO companies you want to be hired. Visiting the office of SEO companies is also great to judge how well companies are doing. Trust your gut instinct; it might save you from anything bad to happen with regards to your business.

(g) Some of the customers of SEO opt for higher price SEO services. This is because they think that expensive services would mean high quality outputs. Most of the time, this is not true. Expensive service may be caused by guaranteed high quality results. However, there are other reasons for expensively priced services. One of them is the inefficiency of the company to operate. They often charge the customers with high priced services to be able to have more budget in acquiring new computer units or pay office rentals.
