The crawling frequency of Google varies from site to site. However if you’d like to force Google to Crawl (or re-crawl) and index (or re-index) a particular page or pages of your website or blog almost instantly, then let’s check out in this post how to do so?
Have you noticed the Cached/Cached Page link in search result pages of Google (example) and Bing (example) when you look for your site’s indexed pages in these search engines? Search engines generally takes a snapshot of almost all accessible pages of your website and stores them in their cache as a backup copy.
When a visitor follows a broken or dead link, then he will see a 404 not found error page generated by your CMS or the server. This type of error page is generated when a search engine bot or a user is able to communicate with the server successfully, but the server is unable to find the requested content!
Affiliate marketing is a major source of income for many high traffic blogs and websites and this is how the system generally works: Your site visitor clicks on an affiliate link or banner >> Go to the website (original or third party) of offered product or service >> Buys the product or service >> You (the webmaster) gets a small amount of commission for referring the customer to the other website.
