I have website in Australia (xxxxx.com.au) and i would like to get good ranking in australian Google (google.com.au). In my understanding, I should get most of links from australian sites, (*.com.au, *.org.au ect.). My question is: can it hurt me if I get some links from non-australian sites? For example, if I have 2 sites, 1st site has 100 links from australian sites, 2nd site has 100 links from australian sites + 100 links from the rest of the world. Which site will be higher in SERP in google.com.au?
I'm not sure if anyone can definitively answer that, but I've had several clients that had pretty much all US links and when I got them more foreign links in order to gain more foreign traffic, their US rankings only kept improving. My personal golden rule is that it NEVER hurts to get a link of any kind to your site. Search engines can't penalize for inbound links, whatever kind they are, because if they did webmasters would use it to harm their competition. Bottom line: get all the links you can
Thank you for your answer In general I agree with you, but on the other hand more links does not mean better. I saw some experiments when people did a web-page with links to deferent websites. Anchor text was unique such as "kjdsfbchj bla-bla-bla". Links pointed to some big sites such as Google and to some small sites with just a few inbound links. In general sites with fewer links rank higher, because percentage of links with anchor text was higher IMHO Google calculates also the weight of links, so if your site has 100 links from pages with PR4, someone has to put even more links with different anchor to your site in order to hurt your ranking. But it is not cost-effective for competitor, because usually there are a lot of competitors So it's better to spend money for your own site. If you have a site with quality backlinks you do not have to be afraid. But if you site has only few low quality links somebody can hurt you, but in this case you do not rank high so nobody will be interesting to hurt you My question is does the same algo works for local Google search?
