Dear webmasters and SEO experts,
I'm given a responsibility of reviving a forum that's been around for 15 years; has seen platform changes from phpBB -> vBulletin -> xenForo -> and now on custom code; built from scratch.
The website was primarily a forum for almost 12 years; and has added other content sections (Quizzes, Projects, News etc.) in the last ~4 years; while the forum continues to exist and drive traffic.
I have been working on improving the traffic to the site since last 1.5 years, but haven't got much success. My observations are as follows -
1. The user generated content on forums has traditionally driven 90%+ traffic to the site through Google.
2. The forum content has ~20% quality content that drives majority of traffic.
3. The remaining 80% of the forum content is thin; but solves practical problems and has backlinks as well. Several of the threads rank well, despite being very thin; and even have backlinks.
What I've done so far -
1. I added 'noindex' to all the thin content based on word-count. This seems to have had no effect on the traffic in the last ~12 months.
2. I ensured all good practices for on-page SEO. Almost every page does 90+ on page-speed and SEO best practices.
3. Linked to the index page of the forum from the front page of the site.
4. Added Sitemap for the forum that excludes all 'noindex' content; and only feeds the content we want indexed.
Yet, there seems to be no noticeable impact on the traffic.
The new content we produce does not get picked up by Google for days (some even months!).
I'd really appreciate advice from fellow webmasters. I'm going nuts with this.
Thanks!
