Web scraping in email marketing

Many businesses have difficulties to bring their products on their market. Often their market it’s easy to be defined. On a defined market you can easy research your competitors and your customers, and what it’s very valuable, you can find details about every potential customer and you can bring him an offer.

A real example:

If your business does cleaning solutions for swimming pools you may be interested by all contact details (contact person, phone number, email address, website) of hotels who have swimming pools near you or even in entire country. If you have this data you can do direct marketing or email marketing (sending services or product offer by email)


Why scraping and why TheWebMiner?

If you read this blog you are one of two things: you are either interested in web scraping and you have studied this domain for quite a while, or you are just curious about this relatively new field of interest and want to know what it is, how it’s done and especially why. Either way it’s fine!

In case you haven’t googled already this I can tell you that data extraction (or scraping) is a technique in which a computer program extracts data from human-readable output coming from another program (wikipedia). Basically it can collect all the information on a certain subject from certain places. It’s sort of the equivalent of ctrl+f, at the scale of the whole internet. It’s nothing like the search engines that we currently use because it can extract the data in a certain file, as excel, csv (coma separated values) or any other that the buyer wants, and also extracts only the relevant data, only the values that you are interested in.

I hope now that you understand the concept and you are wondering just why would you need such data. Well let’s take the example of an online store, pretty common nowadays, and of course the manager just like any manager wants his business to thrive, so, for that he has to keep up with the other online stores. Now the web scraping takes place: it is very useful for him to have, saved as excels all the competitor’s prices of certain products if not all of them. By this he can maintain a fair pricing policy and always be ahead of his competitors by knowing all of their prices and fluctuations.  Of course the data collecting can also be done manually but this is not effective because we are talking of thousand of products each one having its own page and so on. This is only one example of situation in which scrapping is useful but there are hundreds and each one of them it’s profitable for the company.

By now I’ve talked about what it is and why you should be interested in it, from now on I’m going to explain why you should use First of all, it’s easy: you only have to specify what type of data you want and from where and we’ll manage the rest. Throughout the project you will receive first of all an approximation of price, followed by a time approximation. All the time you will be in contact with us so you can find out at any point what is the state of your project. The pricing policy is reasonable and depends on factors like the project size or complexity. For very big projects a discount may be applicable so the total cost be within reason.

Now I believe that is able to manage with any kind of situation or requirement from users all over the world and to convince you, free samples are available at any project you may have or any uncertainty or doubt.

AB test with Google Analytics

An AB test it’s a comparison between two versions of the same page (this testing method is often used in online marketing). With this type of test you can measure what version of a page produces more conversions.

Google Analytics has a powerful tool for AB testing. This tool does all parts of AB testing, including visit balancing over versions of pages (distributes visits to each page version), data registering, reporting and decision.

For doing an AB test with Google Analytics you need to do the following steps:

1. Build an alternative page for your original page (page you want to test it)

2. Registering this experiment in Google Analytics section Content/Experiment

3. Put the code of experiment only in the original version of page.
