Los suministros, la construcción y el montaje, también forman parte de las obligaciones del Contratista. Incluso en la definición más restrictiva de un contrato llave en mano, el contratista es dueño de la construcción de la instalación completa lista para ser operada. Sin embargo, es habitual que el cliente exija al contratista, la contratación de subcontratistas determinados. De esta manera, el cliente trata de asegurarse la calidad de ciertos componentes o negociar directamente el precio con ciertos subcontratistas.


Designed to create a huge amount of traffic at all times, these sites focus on building an audience of millions. These websites promote products to their massive audience through the use of banners and contextual affiliate links. This method offers superior exposure and improves conversion rates, resulting in a top-notch revenue for both the seller and the affiliate.

Cost per click was more common in the early days of affiliate marketing but has diminished in use over time due to click fraud issues very similar to the click fraud issues modern search engines are facing today. Contextual advertising programs are not considered in the statistic pertaining to the diminished use of cost per click, as it is uncertain if contextual advertising can be considered affiliate marketing.

Cost per mille requires only that the publisher make the advertising available on his or her website and display it to the page visitors in order to receive a commission. Pay per click requires one additional step in the conversion process to generate revenue for the publisher: A visitor must not only be made aware of the advertisement but must also click on the advertisement to visit the advertiser's website.

Websites consisting mostly of affiliate links have previously held a negative reputation for underdelivering quality content. In 2005 there were active changes made by Google, where certain websites were labeled as "thin affiliates".[34] Such websites were either removed from Google's index or were relocated within the results page (i.e., moved from the top-most results to a lower position). To avoid this categorization, affiliate marketer webmasters must create quality content on their websites that distinguishes their work from the work of spammers or banner farms, which only contain links leading to merchant sites.

Email marketing is the practice of sending various types of content to a list of subscribers via email. This content can serve to generate website traffic, leads, or even product signups for a business. It's important that an email campaign's recipients have personally opted in to receive this content, and that each newsletter offers something of value to them.

Websites and services based on Web 2.0 concepts—blogging and interactive online communities, for example—have impacted the affiliate marketing world as well. These platforms allow improved communication between merchants and affiliates. Web 2.0 platforms have also opened affiliate marketing channels to personal bloggers, writers, and independent website owners. Contextual ads allow publishers with lower levels of web traffic to place affiliate ads on websites.[citation needed]
This relationship can take multiple forms. You may partner with a brand launching a specific product and receive a percentage of the revenue generated by your referrals. Or, if you work with websites like Amazon, you receive a percentage of whatever purchase a follower makes through your referral links, even if they don't buy the product you were specifically recommending.

Focus on reviewing products and services that fall within your niche. Then, leveraging the rapport you have created with your audience and your stance as an expert, tell your readers why they would benefit from purchasing the product or service you are promoting. Almost anything sold online can be reviewed if there is an affiliate program – you can review physical products, digital software, or even services booked online, like ride sharing or travel resort booking. It is especially effective to compare this product to others in the same category. Most importantly, make sure you are generating detailed, articulate content to improve conversions.
Although it differs from spyware, adware often uses the same methods and technologies. Merchants initially were uninformed about adware, what impact it had, and how it could damage their brands. Affiliate marketers became aware of the issue much more quickly, especially because they noticed that adware often overwrites tracking cookies, thus resulting in a decline of commissions. Affiliates not employing adware felt that it was stealing commission from them. Adware often has no valuable purpose and rarely provides any useful content to the user, who is typically unaware that such software is installed on his/her computer.

I think this email also makes quite a brilliant use of responsive design. The colors are bright, and it's not too hard to scroll and click -- notice the CTAs are large enough for me to hit with my thumbs. Also, the mobile email actually has features that make sense for recipients who are on their mobile device. Check out the CTA at the bottom of the email, for example: The "Open Stitcher Radio" button prompts the app to open on your phone.
An e-commerce merchant wanting to reach a wider base of Internet users and shoppers may hire an affiliate. An affiliate could be the owner of multiple websites or email marketing lists; the more websites or email lists that an affiliate has, the wider his network. The hired affiliate then communicates and promotes the products offered on the e-commerce platform to his network. The affiliate does this by implementing banner ads, text ads, or links on its multiple owned websites or via email to its clientele. Firms use advertisements in the form of articles, videos, and images to draw an audience’s attention to a service or product.
