Compare the services to monitor client sites, or insurance for SEO-paranoid

a Typical situation, you promote the website and instead of the planned positions in the search results get very strange results. But you did everything right? In the process of analysis of the event go to the website of the client and find completely different content. Arguing with the customer is impossible, we love it, but to be able to control what the client does on his website, really want. After all, the blame for poor results of the optimization will be exactly You. Once again in this situation I decided to automate the monitoring of changes on the web and describe how I was chosen for this tool.

Task


To find a program able to automate the monitoring of changes in content on third party website. The program must be easy to use, to quickly and accurately identify changes and visually show them.

selection Criteria


Participating in the selection of only web services because I want to have access to information wherever there is Internet. Of selection excluded those services which do not have any unique properties which simplify the solution of the problem. To determine the winner each service will be measured by the number of points is zero (bad), unit (normal), two (good).

Selection


Сhangedetection.com

The most famous service for monitoring changes on web pages launched in 1999. The project experienced a decade thanks to its stunning simplicity. You specify the URL of the page for which you want to monitor and the email address where to send reports. If the service detects a change, then the mail is sent a notification. In the service available to visualize changed parts of the page. In the personal account it is possible within one account to specify to monitor multiple pages simultaneously. Often the service is very strange, it detects the change on the Russian site, look closely at the screenshot.

  • the Address of each page to monitor, you need to specify in the manual. If you need to follow the website of the company or even worse the online store, add URL links start to monitor it resembles masochism and 7 circles of hell.

Website

Followthatpage.com

The same Сhangedetection.com but there are 2 key differences:
1) Changes on the page seem not in the interface, and come by email. The implementation is debatable, since the visibility of these letters is low, but not if you live in an email client, you may have to taste.
2) the Service may suggest URLS to add to the monitoring on the basis of one of the specified links, but realized it is very superficial, since Followthatpage just pulls the html of all available addresses.

Pros:
the
    the
  • friendly interface.
  • the
  • Automatic proposal addresses based on the specified reference.

Cons:
the
    the

Website

SORGE.pro

After working with SORGE creates the feeling of flying in a space ship. Differences:
1) Service tracks not only the changes in content, but separately track changes in the website structure, meta-tags, leads his DF and checks the status of the domain WHOIS information.
2) Is the only service which not only offers URLS for monitoring based on the indicated references as Followthatpage.com and possesses a robot to index a given site. It's very simple, you specify a link to the home page and SORGE in 1-2 days fully its index, submitting the website in the form of actual structure. Monitoring changes in the structure of the site are maintained separately, allowing you to learn about the facts, if the customer will carry or add a few pages. Thus, if a page is added, the service is not just he will find her, but will automatically begin to track further changes in content. The index is easily customized.
3) Changes in the content not as visual as Сhangedetection.com however, and easy to work with them. It is worth noting that any changes on site for all collected types of information stored in the system that allows you to view the history of these changes. This is useful when changes to the website were made immediately, but in a long period of time.

Pros:
the
    the
  • Better automation and ease for monitoring of the whole site, not individual pages.
  • the
  • Own robot to index configurable.
  • the
  • Comfortable working with large amounts of data (sorting, displaying the change history).
  • the
  • Collection of additional information (site structure, meta tags, direction finding, domain).
  • the
  • Detailed documentation and support for Russian language.

Cons:
the
    the
  • Fully paid. There is a 14-day test period.
  • the
  • Work with service it is better to read the documentation as there are some not obvious things in the interface.

Website

Femtoo.com

The same Сhangedetection.com but a remarkable capability of tracking changes throughout the page, but on some specific parts of it (price, paragraph, table). Similar functionality is in SORGE, but the implementation Femtoo.com a lot more convenient. In the same way as in SORGE there is support for change history, but only available on a paid account.

Pros:
the
    the
  • Easy tracking of individual parts of a web page.
  • the

"And the winner is.." — SORGE. In terms of ease of monitoring sites, from what I tried, nothing better yet. However, I use it only if the site has more than 30 pages. In the case of small promotional sites, it is quite tolerable to work with free Сhangedetection.com. But here everyone chooses his own tools a good choice.

the Way


Wanted to test a project called Trackedcontent.com, it is very well suited under review, however, to get to the interface, the developers are asked to pay money.


If someone dared to pay 49$ for a pig in a poke — describe your experience.

Guys, what software do you solve similar task?
