Business cards certainly should be your primary tool for your gorilla marketing strategy.
We can make you custom cards but don't let them just sit on the shelf - hand them out all over town.
Then perhaps use some of the foot in the door products - the new diesel fuel additives, power steering fluid, PI, MP, etc. I planned on having a section on the MPHD but will do that later. The MP products have solved a lot of problems here in the house and outside. The MPHD is great for sealing off electrical connections from corrosion. I use the silicon spray on computer fans and non metallic sliding parts.
I'm open to hearing if you have any ideas on marketing the new gas engine intake systems. There must be some angle for those we are missing.
I have been updating my compressor oil page. You should also take those seriously. Theres a great deal of income available from them and the AW Hydraulic oils. I sell more Hydraulic oil now than compressor.
Consider making individual pages for specific vehicles. AMSOIL now has so many products available. Just take a Subaru for example - A single page will rank high in the search engines if you recommend a oil, wiper blades, filters, NGK products, cabin air filters, intake air filters and EAAU if applicable. Also oil intervals, transmission fluids, photos, stories, etc. This method would drastically raise your website ranking as you add more of these. It will rank anytime someone searches for a forum of the same vehicle. Basically you are making a forum on that vehicle without all the inputs from others - a blog if you will.
Also consider having separate pages of you own with bypass installs and even antifreeze as a stand alone site. One dealer has a AMSOIL Antifreeze site and sells dozens of drums per year.
More customer satisfaction results with the TRICO Neo-form wiper blades. I now stock the more common sizes as these are a easy sale. I only recommend the Neo-form as they do stick to the glass. Anyone using OEM blades needs to replace them 1-2 year intervals anyway. Get that word out and keep the data sheet on hand.
I mentioned before Youtube videos are easy to make and there are very few Amsoil ones out there. Consider making one application specific such as a bypass install or explaining the intake kits or even oil analysis. they get noticed and if you let me know you have one we can recommend it boosting the popularity. You can make a video with any simple digital camera with the "movie" feature - most do.
