How are backlinks calculated in SERP in your experience. For example if you have say 10 backlinks on the same website, will it have the same value as one backlink? Does the pagerank take much effect. If I were to get a PR4 backlink, would it give better SERP than a PR3? If I were a PR3 website and have 4 backlinks on 4 different PR3 websites, would I be able to become a PR4? Last but not least, are SERP and pagerank updates live or happen in what certain periods? Yes I know i have lots of questions, but the system of SERP and pagerank seems quite a mystery.
It all depends on the other obl on the page to determine the quality of the link as well as relevant links on the page. Rankings change every day dont know when or what time but i see fluctuations all the time.
The best backlinks are the ones from related websites with the highest PageRank. The higher the PR, in your niche, the better the backlink. Good Luck!
Each search engine has its own way of calculating our backlinks. No one can tell how exactly a backlink was calculated.
the exact formula or calculation is unrevealed or it dont even has. nobody knows. it all differs on what each other believes. like me, i do believe that backlinking on 1 high pr ranking site is better than 5 low pr ranking site.. but again, thats just me.
