I consider myself an SEO expert which is why I do SEO consulting with various small and large businesses. I don’t want to name all my clients and certainly don’t want to brag but I have had some big clients in particular in credit check and payday loan industry such as Experian, FreeCreditReport.com, and Pay1Day.com.
Having worked with these clients, I have realized that organic search engine optimization should not be considered as “the solution” but as one of the many venues to bring in targeted traffic.
There are other Internet Marketing Methods such as PPC, Email Marketing, and other lead generation methods that work specially in not so exciting industries such as finance industry. Researching and understanding consumer behavior is important but doing something about it is even more important.
The challenge is that these industries change fast mainly due to as the financial reforms, new rules and regulations, these type of companies often can’t afford to wait months until their organic results to take into effect. They want result and they want it now, before they are further restricted. That is why I recommend them to also invest in PPC, not as a short term solution, but as an ongoing Internet Marketing Campaign. However many advertisers specially the new advertisers often end up paying high costs for PPC which is why many are turned off. See data below: (I copied the table from Search Engine Journal so all credit goes to them.)

So I find it very imperative that as a Search Marketing consultant, I have also invested time into mastering PPC and keep up to date with latest techniques in order to help my clients the best.
There are courses and certificates I have been taking that I would like to recommend. In fact I found a good article on Search Engine Journal on 13 Online PPC Marketing Courses I recommend you to read.
