Suggestions for Reciprocal Links to RF Cafe
It is a well-know fact that search engine rankings are enhanced when quality websites contain reciprocal links to each other. If I have listed your company on RF Cafe and you have not yet provided a reciprocal link, please consider using one of the following prepared links of either text or a graphic.
RF Cafe does NOT purposely provide links to "keyword magnet" sites that exist purely to lure searchers onto their website with the sole purpose of flashing ads in their faces. Those site offer nothing other than a useless list of hyperlinks. Please do not even bother contacting me for a reciprocal link if you run that sort of site. Also, do not send a link request unless you actually work at the company you claim to represent; I am sick of lying website optimizers promising me a reciprocal link on their client's website and then never following through after I list them.
RF Cafe returns very highly, often at the top of the list on page one, for many key engineering and scientific keyword searches, and is regarded as a "high quality website" amongst search engines. Having your website linked to from RF Cafe is a definite asset for you that I am happy to provide, since I personally control every listing. Many requests have been rejected over the years either because they applicant's website is not of the quality that RF Cafe visitors need to be exposed to, or because they are simply not relevant. I'm watching your back!
Thank-you. - Kirt Blattenberger
