For example on a page there are 10 internal links (on the same site) and 10 external links, the link juice is divided by 10 only to the external links or by 20 to both? Thanks
The content within each internal link must be unique to pass 10 link juices. Google consider each links as trusted sources of information.
still don't understand, both internal and external links receive link juice or just the external ones?
Both internal and external links receive link juice. Source: http://www.seoexpertpage.com/improve-seo-rank-old-pages-with-fresh-content-links/ Not really clear as to HOW, but it's encouraged and can increase page authority and PR (whose value has been depreciated in recent months). From a reader's perspective, it makes it more convenient visit related content, particularly in blogs in news sites. It also helps reduce bounce rates by giving clickable links to your audience, thus encouraging them to visit multiple pages.
Internal links are good to provide easy navigation to the visitors. Internal links helps in passing the link juice equally to other pages within your site.
Internal link structure is important, but more link juice will go to the external links, if that's what you're asking?
All of them will get link juice. All these internal links tell google you are linking to other similar type of content (of course algo check that if it is relevant)
The idea is just NOT to overdo many outbound links.. It's natural to link both to your other pages and also to other websites like Wikipedia, HuffingtonPost, etc... Just do NOT link back to your direct competitors
Yeah it does pass link juice. as long as the link are do follow. Also can help the search engines understand your pages with the correct anchor text.
