OP, at least I got your thread on my search results and it's shown on the top:
That appeared on the top because you searched using the main title "Turing completeness and state for smart contract". What OP highlighted is specific post within that page. This is the issue of SEO and how this forum SMF is designed. It's not related to old or new results. I have a suggestion for theymos to solve this....
Well here is a small suggestion what i think can be done in terms of SEO.. not sure how much work need to done by theymos to do this. But i believe this will be very effective and might solve this current issue where google not showing the results. I have faced similar issue and i was able to solve it. I will try to explain it here..
Since the main topic have unique URL with topic id and each post have their own unique URL with msg number. This is good, but it's not good enough for search engines
Main topic:
https://bitcointalksearch.org/topic/turing-completeness-and-state-for-smart-contract-1427885Specific post in topic:
https://bitcointalksearch.org/topic/turing-completeness-and-state-for-smart-contract-1427885.msg14601127If you notice in both cases page title and content remains the same (at least for the first page 20 posts), so there's no way google going to keep track of the full page (#msg14601127 part of url will be resolved on client side to scroll to specific post)
However these days its a normal practice to include the relevant page title for each post or reply. This can be seen in twitter. Twitter changes the title of the page to specific tweet even if its a reply.
Main tweet and notice the title
https://twitter.com/DocumentingBTC/status/1388231761096847364Title of the page
Documenting Bitcoin 📄 on Twitter_ _The Mayor of Jackson, Tennessee, @MayorConger, is talking with state legislatures about allowing the city to mine #bitcoin and adding it to their balance sheet
Subsequent reply and see how the page title changes
https://twitter.com/LastCoinStandng/status/1388233347520897026Title of the page
lastcoinstanding 🔴 on Twitter_ _@DocumentingBTC @MayorConger It's worth keeping in mind that this is another example of how innovative government policy involves not so much creating new incentives but rather just dismantl
Twitter adding main tweet's handle + reply handle + reply tweet in Page Title.
Similar thing can be seen happening on many other website quora is another example.
Suggestion to show different page title for specific posts:If the page is accessed using specific ".msg14601127" in the URL
then bitcointalk should show the different "Page Title" and add some text from the post itself in this case google and search engines will keep separate index of it.
Yes there can be other solutions too but this is the easiest one.. another solution could be starting the page content from the specific post mentioned in the URL. But this will be complex specially in the current SMF.
So when user is accessing the page using this URL
https://bitcointalksearch.org/topic/turing-completeness-and-state-for-smart-contract-1427885.msg14601127#msg14601127Page title should also change like below, google shows 60 characters on the result page but there is no specific limit to characters to be included in the title.
