Question
I am facing duplicate content issue. I want know about the best solution to removing duplicates
We have 19 education levels which are attached with 200 categories please see following URLs. 19*200 = 3800 URLs e.g:
1. /abc/education-8-class. 1. /cds/education-8-class
2. /abc/education-9-class. 2. /cds/education-9-class
3. /abc/education-10-class. 3. /cds/education-10-class
4. /abc/education-11-class. 4. /cds/education-11-class
5. /abc/education-12-class. 5 /cds/education-12-class
6. …………….. ………………………
7. ……………. ……………
But for above URLs, same content is rendering. I want to remove all class level which is no more useful e.g (-8-class) from URLs
And I want to keep correct URL 1. /abc/education, 2. /cds/education
Now my actual URLs will be 200.
I am not able to select which method will be good from SEO point of view.
1.404
2.301 redirects
3. Canonical Tag
Or any others please suggest me
