We identified that in order to maximise UK Radiators relevance for these search queries, we would need to open up the pages to ranking — this would result in their ability to rank and improve visibility (due to increased rankability of terms).
We immediately corrected the canonicalisation issue to allow for the independent rankability of filter pages with good search volume. A combination of opening up these pages to rankings as well as on-page optimisations meant that we were able to greater align with search intent, focus on each page’s relevance & effectively increase sessions to a once blocked area of the site.
To effectively open up new pages with intent, we had to ensure other technical considerations were taken into account so that search engines could find the new pages and the canonicalised filters were not taking up the valuable crawl budget.
