I thought I would just bring something else to your attention; I did take a second to look at your site; you know why I left within just one second? EXACTLY! You have less then 3 seconds to make your first impression on visitors; if your visitors are bouncing off your site at the speed of light, they either found your site by mistake, or they were not impressed with your site, and left, which means? right, they did not trust your site!!! What happens if you have a high bounce rate? right, you can certainly lose rankings! Is google going to keep sending you traffic if you have nothing to offer? nope! I can not say this is your problem, or you could have multiple problems going on at the same time to cause you to lose rankings. I can tell you one thing for sure by just taking a 1 minute look at your link profile; You have quite a few links, and you have almost no authority, what does this mean? This most likely means you are spamming your link to poor quality sites. You also have a massive amount of do-follow links which does not look natural vs your no follow links, and with your site having low trust flow, do you think your site deserves that many do-follow links? I wonder what google thinks? at first glance, your anchor/link diversity does not look to bad, so your anchor/text does not look over-optimized, but whoever is building links for you, consider firing them immediately, as you are getting all the wrong links. I am going to assume at this point google has certainly given you a penalty; Your next move to to hire someone to audit your site, and start disavowing/removing bad links from your portfolio, over time, your rankings may come back, and that may depend on other factors also, but at this point, it certainly looks like you have link issues. Just a little bitty research goes a long way. good luck.
The best way to find suitable brands to promote is by simply using a search engine using: '[Brand] + Affiliate Program'. Some companies run in-house affiliate programs however, this is a very specialist area. Therefore, most companies opt to employ an 'affiliate network' which has already built a large base of affiliates and gained years of experience in running successful programs for clients.
Always disclose your affiliations. Your readers will appreciate your honesty and will feel better about contributing to your earnings. If they sense that you are being less than honest about your affiliations, they are savvy enough to bypass your link and go directly to the vendor just to avoid giving you referral credit (even though the price is the same it's just something people do; strange but true!).
The implementation of affiliate marketing on the internet relies heavily on various techniques built into the design of many web-pages and websites, and the use of calls to external domains to track user actions (click tracking, Ad Sense) and to serve up content (advertising) to the user. Most of this activity adds time and is generally a nuisance to the casual web-surfer and is seen as visual clutter. Various countermeasures have evolved over time to prevent or eliminate the appearance of advertising when a web-page is rendered. Third party programs (Ad-Aware, Adblock Plus, Spybot, pop-up blockers, etc.) and particularly, the use of a comprehensive HOSTS file can effectively eliminate the visual clutter and the extra time and bandwidth needed to render many web pages. The use of specific entries in the HOSTS file to block these well-known and persistent marketing and click-tracking domains can also aid in reducing a system's exposure to malware by preventing the content of infected advertising or tracking servers to reach a user's web-browser.
The two main parties involved in the affiliate relationship are the merchant (sometimes also called “advertiser”), and the affiliate (sometimes called “publisher”). There are different ways to run, manage and promote affiliate programs, which involve more parties in the relationship, but the two main participants (without which the existence of the very marketing channel would’ve not been possible) are: (a) the party that has the product (or service), and (b) the party that knows how to sell it.
And what about joining another company's affiliate program? It's all about extra revenue. Think about your customers' needs: What other products or services would interest your site visitors? Join those affiliate programs. Affiliate programs can increase your sales with no upfront cost to you. It just takes a little time to plan your strategy and select the partners that will have the greatest impact on your business.
