Hi all

Google gives too much priority to fresh and new content. If you update continues fresh content on the website, it will increase your site visibility in organic search. But suppose, if i post some fresh blog and then someone else posted the same blog content but this time this blog have good reputation than me over the internet, will my blog stay on top at this time?

Yes, Google freshness update is part of new algorithm launch by which focus on fresh and unique content. If you post new article in your blog and someone else also posted same like you generally in this condition Google has to give your site first preference and good reputation. If Google is not doing this than you should check your post is really older than another post or not or may be Google has cache that site before than yours or your post is not proper as per freshness algorithms.

Google PR mainly depends on the Links so more the Backlinks you have the more is your page rank it also affected by the rank of page linked to you.

Yes, try to make fresh content continuously and use only SEO optimized articles.
