It increases relevancy: Siloing ensures all topically related content is connected, and this in turn drives up relevancy. For example, linking to each of the individual yoga class pages (e.g. Pilates, Yoga RX, etc) from the “Yoga classes” page helps confirm—to both visitors and Google—these pages are in fact different types of yoga classes. Google can then feel more confident ranking these pages for related terms, as it is clearer the pages are relevant to the search query.
Guest blogging purely for inbound links is a flawed strategy because the value of those links are going down. However, guest blogging for traffic is still an incredibly viable strategy. While that inbound link you get at the end of a guest post doesn’t have as much SEO value as it used to, it still has the value of exposing your content to a new audience.
Remember when you used to rely solely on search engines for traffic? Remember when you worked on SEO and lived and died by your placement in Google? Were you #1? Assured success. Well, okay, maybe not assured. Success only came if the keywords were relevant to your site users, but it was the only real roadmap to generating site traffic and revenue.
