My Link is http://www.pcdocpro.com/blog/saving-your-pc-with-pc-doctor/ Could you please tell me how many times we can submit a same link to search engines? What is a time interval between posting a same link as per right SEO? i.e. how many day, how many weeks etc.
No need to submit the links multiple times in search engines. Submitting links to search engines is a one time process
submit the link is one time process but when u do any changes in your website that time u should submit link second time.
once in a month will be ok, also google visits every site at regular interval so need to submit again and again.
For your information, let me share this interesting tip - You don't need to submit any of your URLs or links to search engines. Let them pick it naturally. Build backlinks from a variety of sites and search engines will find your pages automatically. This gives a good score in the perspective of quality. If you manually submit the links to search engines, it is intelligent enough to note that and consider it as a low valued one. Think about the authority sites. Do you think that they submit their links manually to search engines every time they publish a new page? Never! If you still doubt this fact, search in google "do not submit your website to google" - You will find a blog post from thekeywordacademy.com. Read it and you will find all you need to know about search engine submissions.
yes need not to submitted your site again and again in search engines, Google itself pick your site, if find valuable, this process is only for less valuable site instead of this just try to take good links on relevant sites.
Its only a one time process, if you repeat it again & again then don't do it wondering increase in search engine ranking positions (some might even ban you for submitting the same url multiple times), built proper backlinks and you don't even need to submit your site to search engines - the crawler will automatically follow the backlinks to reach your site and you will get weight-age as well if some high PR site is linking back to your site ...
