Is it OK give too much outgoing links? Some experts said, it will boost your serp, but some said it will danger your site. What do your opinion? Any prove?
As long those outbound links are useful for your visitors then it is ok. Just keep in mind what would you do if you find a page full of links.
the person who said this will damage your serp is right. because lot of spammy out going links are not ok for any site with out enough content
A good rule of thumb to follow is to never have more than 25 outbound links from any page at any time. This includes outbound links created by ad codes (such as google), link trades, and linking relevant information. Pay attention to the amount of outbound links on your pages and in your navigation and try to follow that rule. There isn't a "threshold" of links to determine whether you have too many outgoing links or not. However, too many outbound links and your website does indeed drop in rankings. Also, be sure your pages always have more content than links as well, as some search engine looks at the content to link ratio to determine where to rank your site.
Too much is always bad. Knowing how much you should only a lot for your outgoing links is way better. Though you really have to set some outgoing link for your site too and not just hoard all the link juices that other could be getting from you as well, which is also beneficial in return to your portal.
Too many links will damage your SEO, Google did orginally state 100 outbound links is too much however this has been changed and now depends on what industry you are in etc...
yes can give only 100 outgoing links... take the help from this mattcutts.com/blog/how-many-links-per-page/
Too much link will look like a spam page your visitor will not came again they will treat your site are fake and just west of time make out link with the proper balance
If for SEO yes you always it's dangerous, but for readers who search what they want, maybe it will be better choice and useful.
It comes down to why those links are on your site. Saying you need xxx words of content per link doesn't work. Look at a site like DMOZ that has a huge amount of outgoing links per word of content on the site. At the same time, saying you have 10k words of content means placing a link on a site won't hurt it doesn't work either. Google doesn't value links solely based on how much text is on the same page as them. Work on putting up links that you users will find valuable. Put some effort into increasing the value of those links. Give them good anchor text that makes it obvious as to why you have the link on your site. If you are providing a small list of links, such as "Top 10 Web Hosting Companies", include a short bit of text that adds value for users, such as "This hosting company has 24/7 free phone support and offers fully managed Windows VPS. It also has this, this, and this, which makes it a good choice." If you want to do a large list, such as the "Top 100 Web Hosting Companies", consider how you could break it down a bit, grouping links together based on relevancy that your users could appreciate. An example on how to do this would be to have a page with the title "Top 100 Web Hosting Companies" that you have a bit of intro text on and then provide links to pages where you have your groupings, such as "Jump to Web Hosting Companies that offer unlimited bandwidth". Breaking up bigger lists into highly relevant groupings allows your site's users to see a small list that is exactly what they wanted, rather than a big list where they have to scroll through it and try to figure out where to get the links that they want. Google sees it that way too and, with your groupings being separated into different pages, can send web searchers right where they want to end up. Don't put too much thought into having "too many" links on a site. Instead, think about how to increase the value to users for the links that you have, and whether or not the links you have really give value to your users.
I agree with this. The more outbound links you have going the more you are susceptible to getting spammed.
