The advantage of the validator is a high degree of accounting for passenger traffic in transport, the ability to accurately control visits to closed offices and enterprises, and the relatively inexpensive cost of servicing the device.
Moscow ground transport
The first turnstiles with validators in ground public transport in Moscow, as part of an experiment on the implementation of an automated travel control system (ASCP), appeared in 2001 in the Zelenograd administrative district on bus route No. 16. By mid-2002, the system was extended to all Zelenograd bus routes (municipal subordination), and from September 2007 to all surface urban public transport of municipal subordination.
Saint Petersburg
Manual validator PK-001
Since January 2007, on most social public transport routes in the city, conductors have a device for reading information from travel documents - a validator. Later, validators appeared for route drivers who do not have conductors.
By 2011, most city buses had switched to the new electronic fare control system (ECOP). This system provides for the presence of stationary validators in the passenger compartment on the handrails (from 4 to 8 pieces), which allow the passenger to independently pay for the fare (validate the electronic travel ticket).
SECOP includes two types of validators: simple and informational. Simple validators have an LED indication that informs the passenger about the following events:
- The validator is ready to read the electronic travel ticket.
- Travel paid.
- The travel has not been paid for (for example, the validity period has expired).
- The electronic travel ticket has been re-attached (the fare on this route has already been paid for).
- The validator is blocked by the controller while the fare is being checked.
Indication of validator operation
Information validators have an LCD display, which, in addition to indicating events similar to a simple validator, can display information about an electronic travel ticket (validity period, travel resource or balance, depending on the type of electronic ticket). To obtain such information, you must first pay for the fare, then again attach the ticket to the information validator. The validator will show that the ticket has been reapplied, and after a while it will display information about the EBP resource.
Other cities
In Krasnoyarsk, using a plastic electronic card, privileged groups of the population can pay for travel on city public transport from the beginning of 2008, all other citizens - from November 2010. Conductors of all buses, trolleybuses, and trams have portable readers (validators). You can top up cards through multifunctional payment terminals, as well as at city post offices.
In Kemerovo, you can pay for travel this way since January 2010. The system has been introduced on all buses, trolleybuses and trams in the city. When paying with a transport card, you can save up to 1 ruble per trip.
In the city of Almaty (Kazakhstan), since January 2008, the fare payment system through a validator using electronic card or cash is valid on all trams and trolleybuses in the city. On buses this system has not become widespread; validators have been installed on many buses, but do not work. In 2011, existing validators were introduced on several bus routes and accept only iron money, since the bill reading system and eCash system magnetic card replenishment points do not function, and are often completely absent.
In Yekaterinburg, the E-card transport card was introduced at the end of 2009. The system has been introduced on all trolleybuses, trams and buses in the city. Validators are located at the conductors or installed on the vertical handrail on the rear platform. Some minibuses are also equipped with validators. You can also pay for travel in the usual way. since 2012 operator MegaFon launched a service for paying for travel with mobile phone in public transport in Yekaterinburg. True, at first such a service was implemented only in the Yekaterinburg metro, but now such an opportunity has appeared in ground transport. Thanks to new service MegaFon, you can pay for travel from your mobile phone in all types of ground public transport in Yekaterinburg, on a number of commercial routes, as well as at all stations of the Yekaterinburg metro - wherever the E-card is accepted.
In Yaroslavl, since 2010, a payment system has been introduced for all types of public transport using a refillable electronic travel card (payment is made one month in advance). Validators are provided to conductors and drivers. It is also possible to purchase regular single-trip tickets.
I want to devote today’s article to site validation (that is, HTML). First, let's define what this term means! Site validation is checking for syntax errors, checking tag nesting and other criteria. As a rule, validators (services for checking sites for errors in document structure) check HTML code for compliance with a certain standard, which is indicated at the very beginning of any HTML page in the first line. If you didn't know what it was for, now you will know! 🙂 But why, exactly, is this validation needed and what does it affect?
“What is site validation?”
As I said above, validation is the compliance of HTML code with certain rules and standards. XHTML was replaced by , which made life much easier for developers. The thing is that in the XHTML version the syntax was very strict. If in HTML5 you can write a wrap tag
both without a slash and in this form
, then only the last option will be correct in XHTML. HTML5 is not so strict, and besides, many useful tags have appeared, but that’s not about that now :)
“What does site validation affect?”
Now let's answer the second question.
Site validation allows you to monitor the correct display of the site in different browsers. For example, if you do not close the tag or make a typo somewhere in the code, then the same page may be displayed differently in different browsers. Also (CSS) may not appear as you expected. Therefore, it is necessary to monitor this closely.
Also, I couldn’t help but say that validation affects search engines: search engines give preference to sites with valid HTML code. Keep this in mind!
Well, have I convinced you that website validation is really necessary? Then we're done with theory and let's move on to practice!
Validation Check Methods
I wrote about each of the methods detailed instructions in the form of text, and also, if someone is too lazy to read and understand, I made a video 😉 .
1 way. Service validator.w3.org
The essence of the first method is to use a service to check the validity of the site. How to check the validity of a site using the service validator.w3.org:
Follow the link above and select the version Firefox browser and click on the “Download” button. Then select the required operating system and install as a regular add-on. (those who don’t understand, watch the video :)
2. Plugin for Google browser Chrome -
Here you need to click on the “Free” button and then click “Add” in the pop-up window.
Happens here too normal installation additions.
4. Plugin for Safari browser -
Installation:
- Unpack the archive with the plugin.
- Copy the file "Safari Validator.webplugin" to the folder where the browser is installed, then /Library/Internet Plug-Ins (create a folder if it is missing)
- Double click on the Safari Validator.safariextz file.
- Restart Safari browser.
I tell you how to install the plugin in Firefox and how to use it in the second video:
Conclusion
That's the whole article. I hope the video materials, as well as the text information that I presented here, will help you improve your site and make it even more “attractive” to search engines 🙂, because we all strive for this. If you have questions or difficulties at any stage, write in the comments, we’ll figure it out together! Anyone who has read to the end of the article and done everything I wrote about has already improved their website and the result will not be long in coming. 🙂
We have released a new book “Content Marketing in in social networks: How to get into your subscribers’ heads and make them fall in love with your brand.”
Micro markup validator - software, which checks web page markup in any format and on all existing languages programming.
More videos on our channel - learn internet marketing with SEMANTICA
Everyone loves to travel, especially to hypermarkets. So you, without breaking generally accepted trends, go shopping. You need to find juices, water, cookies, bread, socks, diapers and other things. But the store is too big, and it may take more than one hour to walk around it and find what you need. Another option is to contact a hypermarket employee, but there are a lot of purchases, so this method is not always applicable. It is much more convenient to navigate by signs that are located between the rows and accurately indicate the placement of products in the department.
In order to select the current and useful information, search bots also use certain algorithms to select information for users.
What markup is considered correct?
The correct semantic one is considered to be one that is well received by search engines such as Google, Yandex, Bing and Yahoo. We have all encountered more than once that these services index information in completely different ways, so most often we pay attention to thoughtful, catchy and clear snippets.
Therefore, before implementing micro markup on the site, you need to determine the type of your data. For example, in a product card for an online store, you need to mark the price of the product, its name, description, image, reviews, rating. This way, the search bot will be able to understand what exactly is on the page without any problems and make it more relevant.
There are several services to check the correctness of micro markup:
- Google background check tool;
- micro markup validator from Yandex;
- validator.w3.org;
- validator.nu.
If your page has been validated on one service, then due to differences in search algorithms, it may not be passed on another. In order for search robots to correctly index your markup, understand its structure and settings.
Why do you need a markup validator?
is a semantic markup standard designed specifically for structuring information on a page for processing programs. In our case, microformats allow us to indicate to the search robot the semantic meaning of individual page fragments and are used to convey information about the organization, products, reviews, and recipes.
Any page on the Internet consists of HTML tags, which tell the browser how this or that information will be displayed, and micro-markup sets search engines a certain framework within which they need to search. Therefore, it allows you to achieve better page relevance for search robots and users. And most importantly, semantic micro-markup allows you to improve the appearance of the site in search results (snippet).
Snippet without markup:
Snippet with markup:
The validator checks the correctness of the entire process and identifies errors made when working with the code. After all, if it is not properly checked, this may negatively affect the indexing of the resource and, even more so, your income. Therefore, it is a must-have tool for any programmer or webmaster.
Pages without errors in the code are the dream of any website owner, since the results of high-quality work will clearly affect your positions in search results. This will not affect a site with 30+ positions. However, when the search engine shows 15th place, and not 3rd as we would like, this means serious shortcomings that entail material costs.
Most often, users who start using such software do not clearly understand how the site's micro-markup affects rankings. Yandex responds that it acts only indirectly, while the site becomes more attractive to the user, its audience becomes larger, as a result of which its position will increase. He clarifies that you should not expect results in the coming days, since they will appear only within one to two months.
How does a markup validator work?
To check the page you need to enter the URL of the document being checked or paste required code in the form below.
In the “Check Results” column, the program will display the identified defects and their location.
There are two cases when an error message is displayed:
- if the validator cannot recognize the markup;
- if the markup does not comply with the standard and cannot be recognized correctly.
The message that "page not found" means that the page does not exist. Perhaps the page is unavailable to the search engine due to a service error, or due to security restrictions.
This will provide a list of required fields that are not taken into account in the work sent for review.
Google tool
Google, in collaboration with Yahoo! and Bing for the first time in 2011 tested their invention - a micro markup validator, which Yandex later joined. As a result, the whole world began to use the validator. The validator is constantly being improved and its functionality is expanding.
How to check:
1. Using a URL. Suitable for owners of active websites. Copy the link and paste it into the field provided for it.
2. When HTML help fragment. This option is suitable for those who are just creating a website and storing it somewhere on local server. The steps are the same - copy the code and paste it to check.
Google supported markup formats:
- microdata;
- microformats;
Supported types of markup information:
- reviews;
- goods;
- companies;
- organizations;
- Events;
- music.
Yandex tool
Over the past four years, programmers have increasingly begun to use semantic micro-markup - about 15% of RuNet pages are marked up. Therefore, the need for validators has increased. And Yandex does not stand aside from new developments in this industry. It, unlike Google, is developing more rapidly and creating new universal tools.
Supported formats:
- microformats;
- Schema;
- HTML;
- Open Graph.
Data types supported by the Yandex validator:
- goods;
- prices;
- addresses;
- organizations;
- articles;
- music;
- test drives;
- drawings;
- video clips;
- recipes;
- movies.
The microdata validator allows you to check the correctness of data structuring. It simplifies the work of optimizers and helps to correctly mark up content on the site. This makes the information about the page beautiful in search results and attracts visitors to the resource.
Let's talk about code review tools. A special tool that is created for this purpose is called a format validator. HTML will be used as an example. A validator for this markup language is quite suitable for explaining the principle and giving an example.
Why is it needed?
It happens that when you write program code, everything seems to work correctly, but it doesn’t hurt to check. So, let's say we created an HTML page. When we think about a validator, it means that we are interested in how well it is made from the point of view of the accepted standard (the better, the more correct and on more computers it will work).
Setting up conditions
The severity with which the page will be checked is specified in the tag. If it is not specified, it will be examined most thoroughly, and in the report the validator will indicate all errors and deviations from the standards. Also keep in mind that the verification will be carried out according to HTML5 rules. To indicate a different version or mitigate the search for deviations, use this tag. By the way, in addition to the HTML version, there is also a CSS validator. It will allow you to check the construction of the cascading style sheet and its compliance with the latest standard. If you are already interested in this topic, it is better not to neglect this chance.
Directions for checking the DOCTYPE tag
On this moment There are the following types of checks:
- Strict according to the latest standard.
- Transitional.
- Strict.
- With frames.
By the way, it is advisable to always specify DOCTYPE. After all, if this is not done, different browsers, which various settings, will display the layout of the page differently. AND required file It will be very ugly to display. It should be noted that this only affects the visual component, while performance is not affected.
Let's say a word about mistakes
Even when checking a small document, a code validator can find many programmer mistakes. Is it necessary to eliminate them all? No. Most technical errors are not critical; the most they can do is slow down the site a little. Although, if this parameter is valuable to you, you cannot ignore them. It should also be noted that some errors may appear already at the time of compilation by the PHP interpreter.
Other elements
The fact that the HTML validator checks the code is certainly good. Are there any special features regarding RSS feeds and cascade feeds? CSS tables? Yes, there are validators for them too. Remember: they only check that the code complies with standards. And they don’t care what’s written there. Therefore, if you are primarily interested in the quality of the page and site, you need to check them too.
Online check
In order not to disperse their efforts across various programs, many developers have chosen an online validator. What is it and how does it help? Such services are usually already configured to check all three components (RSS feeds, CSS and HTML). Their versatility is worthy of praise. But it is better to check the correctness of HTML composition separately again. If we talk about the advantages of online services, it should be noted that there is no need to copy the entire code. Just enter the site address, and within a moment errors will be displayed. There are also browser extensions that can also partially or fully check whether the open page accepted standards.
What is included in validation?
This process is divided into several parts:
- Search in progress
- The nesting of tags is checked. They always close in the reverse order of how they came off. And if something is wrong, you will be notified.
- Checking for compliance with the specified Document Type Definition. The automation scans and determines whether everything (tags, attributes) is written correctly, relative to the version of the markup language that is declared.
- Check for foreign elements. A search is carried out for what is actually in the code, but is missing in the Document Type Definition.
It is necessary to understand that these are all logical checks. In this case, it is not important how the validator is implemented. What does this mean in practice? If at least one check fails, the code will not be considered valid. At the end, every serious program will provide recommendations on what needs to be fixed (and may even tell you how to do it).
Arguments for holding
The main reason why a markup validator is needed is to ensure cross-browser compatibility for a site or its individual page. The fact is that each program that helps you browse Internet pages has its own parser. Therefore, the only way to be sure that the code will function correctly in all browsers is to run it through a validator. What else does this give?
The fact is that each browser has its own mechanism for correlating errors in program code. Therefore, perhaps he will be able to correct the situation with an invalid program, or he may make everything worse. These were arguments for, but there are also against.
So, it is worth noting that the markup validator is very strict. And browsers can fix some errors on their own. Therefore, if the first priority is the task of proper operation, the appearance can be partially ignored.
Reviews using validator
What does this mean in practice? Compared to what is used in real applications, the validator is extremely demanding. Of course, he may show some errors that interfere with normal work, but you still shouldn’t try to please him completely. It is also often pointed out that checking for foreign elements does not always go smoothly. But these also include custom attributes that are not recognized by standards, but are used by developers to facilitate production processes.
If you have doubts about aesthetics appearance pages, then they are in vain here. So, if you specify a Doctype, the browser parser will be switched to a certain mode. But this will not lead to the fact that it will be loaded, and the code will be checked for compliance with it. Therefore, browser parsers are already configured in advance for the fact that there will be a certain lack of code validity. The same is true with user attributes: they are successfully recognized and processed. An example is ARIA technology. It works with attributes that complement the semantic meaning of the code, which is why the validator curses. What is this: good or bad? On the one hand, the code works and provides special abilities. On the other hand, there is a deviation from standards. But in the case of ARIA this is completely justified.
Conclusion
In the end, I would like to say that everyone independently chooses whether to use a validator or not. Within the framework of the article, the features and nuances of this step were described, and the decision remains with the reader.
