Just a feedback: It would be great if we can avoid thin content using noindex tag.
Indexing of Safe mode can be disallowed using noindex tag.
Search Results , guess we do not need to show in the SERPs. May be we can noindex it too.
If we manage to remove thin page, we can do better in SEO.
Duplicate content can be tackled down.
may be we will see more indexed page, but less excluded pages.
How we can make this better?
I understand this will take time, and need to be done carefully.
Step 1. We need indentify which pages are likely to create duplicate content
1. /search?* 2. /c/ 3. /u 4. /top* 4. /latest?* 5. ?preview_theme_id=* 6. *?* 7. /tags*
Step 2. We should apply noindex wherever we see thin pages.
Step 3. We should use noindex tag instead robots.txt disallow rule.
Step 4. We need avoid creating duplicates content pages, like
/latest (homepage & latest).
or /guidelines = /faq as possible as.
Step 5. We also need to avoid indexing of thin pages such as safe mode.
Thanks & Regards,
