There are many programs for parsing data from websites. They have different functionality, level of convenience and, of course, different prices.
Let's look at the 5 most popular services that allow you to parse data from a website, and check how convenient and efficient they are.
To evaluate the functionality, let's consider loan phone number data what an ideal parsing program should definitely be able to do:
Search for broken links
Specify incoming and outgoing links of the page
Indicate the type and chain of redirects
Be able to filter pages:
use regular expressions;
crawl according to robots.txt, meta robots, canonical, etc.
Parse individual links
Detect duplicate Title, Description and H headings
Specify the nesting level
Specify H headings and their number
Specify server response code
Be able to change User Agent
Specify Title and its length
Description and its length
Keywords and its length
Canonical
Meta robots
Specify Alt and its length
Indicate the content type
Thus, we have 17 main requirements. We will separately consider the availability of additional functions, as well as the ease of use of the service and the speed of its work.
To determine the speed, let's consider a site with about six thousand pages. At the same time, about 1500 are allowed for indexing (note that the resource has open scripts, and therefore it can parse them too). For each program, the parsing conditions will be the same.
1. Xenu's Link Sleuth
Xenu's Link Sleuth
Helps to find broken links, so the functions are significantly different from most of the services below. The program is free, which is a big advantage.
It solves its main task perfectly, although there is a drawback: it does not indicate links from and to the page. It will not be possible to conduct a detailed analysis with its help. But if you need to find out about the presence of broken links on the site and the nesting level of pages, use Xenu's Link Sleuth.
When you need to get more information about a site, choose another parser.
It took 17:59 minutes to parse the site. Not as fast as I wanted, but quite ok.

2. WildShark SEO Spider
WildShark SEO Spider is a free Western program. Very simple and easy to use. The functionality is wider than Xenu's Link Sleuth, but the functions are not enough. With the help of the service, you can quickly determine the technical condition of the site. To perform a more thorough analysis, you will need another program.
A distinctive feature is the presence of tips on the right side of the screen, where the error and general information about it pop up. In addition, the service can parse OG micro-markup. This is a fairly rare function that is not often encountered.
Parsing data from the site took 9 minutes. Considering that the program is free, this is an excellent result.
