I like to give feedback, indulge me.
I have a site that has been neglected for years.
It's a forum, it was full of spam, no moderation, no active participation, no editing of titles, no mobile ready, no curation, no https, nothing, completely ignored.
Yet, it did get some random valid new posts, every other day.
In a constant search for procrastinating my other work, and as a kind of an experience and challenge, I decided to give it some care:
- made it responsive
- removed ads
- cleaned up and made the url structure more friendly
- updated code to give hard 404 (it was giving soft 404)
- updated code for every page to have a unique url through 301 redirects (no duplicated content)
- added some meta information
- implemented https
- moved it to a SSD dedicated server with Varnish (made it fast)
- removed all non essential files to reduce requests and page size (average 13 requests page size 70KB)
- cleaned up the content (removing duplicates, redundant, merged, spam, etc.)
- edited most recent titles, to something readable and describable (removing ALL CAPS, "help me" and such)
- implemented new more specific categories
- implemented tags for a "same topic" funnel
- implemented schema.org
- removed several pages (search results pages, profile pages, login, etc.) from Google index, keeping only the "juice"
- improved significantly the internal search pages
- did some curation
- updated the design to the millenial trend where there's nothing to click on
- implemented AdSense's matched content
- got an eye on search console everyday
And... the result after 3 whole months?
Nothing.
Some traffic flutuations, but nothing worth noting.
That's it. That's my feedback.
In a sentence: DON'T BOTHER. :D
My conclusion: if the content is good, unless you're doing something really wrong, Google will take care of it.
To me, there is no amount of SEO good practices that will pay your stress/work, just have good content, keep it simple and working.
Will I see a change meanwhile? I'll keep you posted. :)
