SEO isn’t just about high rankings, boosting page rank, getting keyword anchor text links and it’s far from dead despite the onslaught of Google Ads. Site architecture which involves the crawling and indexing of pages isn’t the first thing that springs into a clients mind, though it’s importance for onsite SEO shouldn’t be overlooked.
Recently after another re-development and site migration I was asked to review a site that was experiencing problems. It won’t be the last site to experience a drop in traffic after a redesign, as poor site migrations seem to be standard practice. The client was able to spot an issue fairly quickly, not least because there was a drop in the conversions.
Google Analytics also showed a big drop in traffic year on year, and looking in Google Webmaster Tools there was a noticeable drop in the number of indexed. Some important pages weren’t being indexed.
