Say, I am making a directory site for spas... and there are many already.. and I can do a better SEO with backlinks, etc... Will that detailed page be treated as duplicate，as the data source (address, phone, etc) might be same, or from similar database? Will that be unfair for the late comers? What is the best way to proceed? Change wording, adding information?
I am not "the" Google expert, in fact they make me want to puke, but a guy named Jonathan Leger wrote a blog on his research and then proved his point by example. What he said was basically that all this talk about some algorithm that can actually decipher duplicate content is a fallacy. Then we went on to drive it home by doing numerous blogs with exactly the same content and applying various SEO strategies and they all ranked no problem. He cited several other PR4's and up that were made of entirely duplicated content and so the story goes. Here is his url. I don't have the exact link to the study on the subject, but it should still be there. http://www.jonathanleger.com . Then my question would be how do they find "duplicate" content for copyright infringement. I would guess that they are looking for it specifically and they target that in the algorithm. So that is my "devils advocate" response. My belief is that Jonathan is correct. I do look at the possibilities though. Hope that helps.
BadBoyzStudioz, thank you. His research is interesting, I do see tons same article on the search results a lot... Mine is more specific.. there are yahoo directory, Google directory, YP, many use similar database... So the similarity is there... So we have a directory of spas... many do have similar content... I don't think there is copyright issue there even they share same database and allow to publish.. So the issue is really who can rank high? And I doubt one site can sue the other as well... I just felt how we can get the information overload less and more efficient... Of cause, I dont think the first person made the spa directory the King,, and the new comer can do much better job designing site, marketing, promoting and getting on top..Will the first have rights to... say, ask Google to deindex 2nd one... or sue 2nd.. both have complicated consequences....
I think it's not problem. If you make a directory website or something like that. Then someone else can do this, but dont use exactly your content (for example: catelogy 1 is: Webmaster, catelogy 2 is: domain and hosting, and they have a site copy exactly what on your site. They copy from post to post - then it's problem) You cant say if they have same ideas like you (like google make search engine and yahoo do same things. It's not duplicate ) Am i wrong?
Here is the thing about copyrights... Unless you can lawyer up enforcing them is very hard. They can write your IP and hassle you. In that case send the IP this letter... http://www-2.cs.cmu.edu/~dst/Terrorism/form-letter.html That will keep 'em busy for awhile.
I was wondering if all top pages for a specific query have similarities... And Google has no other ways other than links, etc.. I don't think Google wants to get int copyright business. However, if one webmaster complains to Google of duplicate content, what Google will do? I do think they have the power of deindexing....
Google doesn't tend to index the same content again...if it does then its deindexed as a sand box effect.
Duplicated content get indexed, but as "similar results". Try to rewrite as much as possible to avoid this.
Also let me tell you that Google IS ABLE to detect similar content. Just go to Google News and see how they was able to detect it.
actually there are several places that you can find duplicate content. check copyscape.com. They will show you which sites and how many words are dupicated with a single click of a button (after typing in the url) There are some steps that you can take to see if your article is duplicate content yes even the ones that you thought of yourself are sometimes pretty close to what someone else has already wrote. Her are the steps: copy article to an html editor no need to make it pretty just as long as the text is there it will suffice. I have even don it with no punctuation and it worked like a charm. then load up the html file in a subfolder on your server name it test or test1 or something *** I know some might not have this capability. So if someone could please find something that is comparable to this then please post a quote to it *** now go to copyscape.com and type in the full name ***.com/test/****.html and then click enter. it will give you similar results like that of a search page but it is self explanatory just click on one of the returned and it will give you all of the information you are needing to be worried about duplicate content. * IF THERE ARE NO RESULTS THEN YOU HAVE A UNIQUE ARTICLE * check out 3gwriting.com it is going to be a transparent testing place for marketing. primarily article marketing and bum methods but you and others will be able to see the results and the input that goes into it for free. It is also geared toward new to intermediate marketers but all are welcome and asked to come to show support. A win/win situation is always better then "what's in it for me?" you get what you give and give what you get that's the way it's always been
My dear friend..."similar pages" is altogether different concept...don't spread misinformation It is mainly based on what sites link to you, and what sites you link to. Aah...copy-pasting to increase post count!
