There is an irony in google preventing web scraping given that their business is pretty much built on web scraping.
That said, automated research fascinates me, I wouldn't want to scrape Google to make my own Google, but rather to make private repositories of information that I can then query efficiently. I would love to find any kind of scriptable search engine access, paid or free. Not entirely sure how to look though.
No matter how well-intentioned you are, if you write your own scraper and have it abide by robots.txt, you'll never get nearly as many resources as Google or Bing. Many websites approve only their scrapers and ban everything else outright.
I don't have anything against the large search engines, it's just not really easy to say no to their scrapers for most websites.
That word, I don't think it means what you think it means.
I don't think that making a scraper will make you competitive with Google. If you can make a site ranking algorithm that compete's with google, on the other hand, you might have a chance
Er, ughm. I mean,
Ding ding ding!
The one reason Google is competitive is due to them taking advantage of the cheap labour that keeps track of ranking manipulation.
Luckily most of the search problems have nothing to do with ranking manipulation.
From one side it's along the natural-language interface from Alexa or alike; from the other side it's an interface of search for people who generally need access to information.
If Google exposed interfaces similar to Elastic Search - the search would never be an issue anymore; but it would not be easy to use by the users.
You and me both :)
I still haven't gotten around to do much about it, but for example one thing I've been thinking about is to have my system integrated with my desktop so that it has some situational context.
For example, it would look at the programs that I have currently running.
Let's say that it saw that I had PyCharm open where I was editing some Python 3 files. Furthermore I also had Vim open where I was editing some HTML, CSS and JavaScript files.
It would maintain a list of all items that had been in focus during the previous 30 minutes or something.
When I then searched for let's say sort list it would look at the list and see that most recently I had been editing a Python file in PyCharm so result number 1 would be how to sort a list in Python 3. Before that I had also focused Vim with a JS file, so sorting arrays in JS would be result number 2.
Results:
1. Python 3. Sort list "a_list". In-place: a_list.sort(). Build new sorted list from iterable: b_list = sorted(a_list).
2. JavaScript. Sort array "an_array". In-place: a_list.sort(). Create a new shallow copy and sort array: let another_array = an_array.concat().sort().
And if the system was even smarter, it would also be able to know details about what I'd been doing. For example it could see that while editing a JavaScript file I had most recently been writing code that was doing some operations with WebGL, and before that I was editing code that was changing style properties and before that something that was working with Canvas, so if I then search for blend, it would use this information.
Results:
1. WebGL Lesson 8 – the depth buffer, transparency and blending. http://learningwebgl.com/blog/?p=859
2. Basics of CSS Blend Modes. https://css-tricks.com/basics-css-blend-modes/
3. CanvasRenderingContext2D.globalCompositeOperation. https://developer.mozilla.org/en-US/docs/Web/API/CanvasRende...
Something like that.
And because it's for the limited amount of things that I am interested in and developed for myself only (as opposed to trying to give super relevant information for every person in the world), it might be doable to some extent.
Here is a book that might be of interest to you; Relevant Search. https://www.manning.com/books/relevant-search. I bought a copy myself but have yet to read it.
They cannot. Googlebot & some other search engine bots (like Bing's & Yandex's) get special treatment in various websites. This includes things like ban on non-whitelisted scrapers & bypassing paywalls. If you are not already established player in the field, you would not get able to scrape the same websites as the established players can.
Basically it was anti competitive to grant certain privileges to major players around 'public data,' but to block smaller players.
No telling if/when ramifications from that decision (last year) hit existing anti scraping measures, though.
Unfortunately that is not the case. Many paywalled sites will let googlebot index their content but block other crawlers.
They may have good reasons for doing that in some cases, but as a consequence the level playing field you're talking about no longer exists.
Also, the purpose of using Google as part of some automated process is usually not to compete with Google's search engine, but to complete some specific and limited task.
I don't understand why Google does not have a general search API offering. I'm sure many people would happily pay for it.
A search monopoly is not good for website owners. It makes us very dependent on the whims of that monopolist.
If you block all crawlers that don't already have a large market share and send back a lot of traffic, you're killing any possibility for new competitors to get a foot in the door.
Also, you're killing any chance for something unexpected to happen, such as someone having a great idea based on crawled data that could change all our lives for the better without ever sending traffic to your site.
Now, I'm not telling you what you can and cannot afford. If crawlers cost me a ton of money that I don't have I would certainly act exactly like you suggested.
Very true. Only allow Google and you are helping them to build their monopoly. And if they have full monopoly they do what they want - including asking you money to be included in the search results.
Doesn't that infringe upon Google's own rules? I always thought Google didn't like it when sites served its crawler content that's different from what users get when they follow Google's link.
But it no longer works at all sites. Maybe the rule has been dropped now that paywalls are becoming more popular (with publishers that is)
I think bing is close to Google in quality. Some people might even like it better. On the other hand I think DDG is the Sprint of search engines.
Google used to have a search API and they discontinued it because they said most of the people who used it were SEO people.
People who do pay-per-click are into A/B testing and other quantitative testing. Google is all for you doing that if you pay for advertising. Their mainstay of anti-SEO is doing arbitrary and random things to make it impossible for SEOs to go at it quantitatively. (They have patents on this!)
One reason so many sites go to a harvesting business model is that once a site is established you can make the slightest change and then your search rankings plummet. If you depend on search engine traffic it is a huge risk that you can't do anything about unless you are about.com (bought a 'competitive' search engine and just might be able to make an antitrust case against Google.)
I've been interested in switching to DDG for a while but as a former Sprint customer, that statement scares me but maybe some explanation from you might understand your opinion better.
Often I do get a good result on the first page but often results #1-#N vary from third rate to non-sequitur and then result #N+1 is the one that should be at #1, where maybe N is drawn from Uniform(3,6). I see this so much I can't imagine it is an accident. If anything it seems to be 70% more evil than Google.
The real difference is non-technical things. Google filters out unflattering results and one side of anything even remotely political. It's a nerfed world, kind of like a Disney theme park. I'm an adult and I don't need to be led with blinders to the googly viewpoint.
Isn't DDG just a Bing wrapper with a few frills in the results?
He is not selling advertising.
He is not even running a public website.
Google is preventing you from using automation to create private (i.e. personal) respositories of information, even when that information is public and (ironically) Google itself relied on automation ("bots") to collect it.
That's what Apify in original post does - including a public database of scrapers, so there is a high chance you could use already finished scraper :).
