4)Difference between average CPC & Maximum CPC?
A)Average CPC: 
The average amount that you've been charged for a click on your ad. Average CPC is calculated by dividing the total cost of your clicks by the total number of clicks.

·         For example, if your ad receives two clicks, one costing $0.20 and one costing $0.40, your average CPC for those clicks is $0.30.

·         Average CPC is based on your actual CPCs (the actual amount you're charged for a click on your ad), which might be different than your maximum CPCs (the highest amount that you're willing to pay for a click).
·         To see your average CPC amounts, look at the "Avg. CPC" column in one of the tables within your Campaigns tab

    Max CPC.:

A bid that you set to determine the highest amount that you're willing to pay for a click on your ad.

·         If someone clicks your ad, that click won't cost you more than the maximum cost-per-click bid (or "max. CPC") that you set. For example, if you set a $2 max. CPC bid, you'll never pay more than $2 for each click on your ad. The actual amount that you pay is called the Actual cpc

 and is shown in your account's "Avg. CPC" column.

·         A higher bid generally helps your ad show in a higher ad position on the page.

·         You'll choose between manual bidding (you choose your bid amounts) and automatic bidding (you set a target daily budget and the AdWords system automatically adjusts your max. CPC bids on your behalf, with the goal of getting you the most clicks possible within that budget). With manual bidding, you'll set one maximum CPC bid for an entire ad group, but can also set different bids for individual keywords.

The Different Types of Back Links

Inbound back links– are links that point directly back to any of your web properties, that in turn , point back to your website. This allows search engines to crawl your website as major search engines discover new sites and content via anchor links on established web properties, websites, and web services.
One way backlinks– they pass page rank and link juice to web properties. These types of anchor links are used for directing search engine crawlers “one way” to follow these  links back to your website, blog, social profile, media release or press release, videos, web 2.0 properties, do follow social bookmarking profiles, local directories, established web directories, and / or any other web property.
Reciprocal backlinks– this type of backlinking is the act of basically exchanging links between different websites and web properties. The phrase, “I’ll scratch your back, if you scratch mine” theory should help with explaining what a reciprocal back link is. This method is not as popular with search engines as it used to be back in the day because they see this as artificially boosting the page authority.
Do Follow Backlinks– this is the act of building links to your website or web properties by using other websites, web properties, and web services that allow the passing of pagerank and link juice from their website to your website or other web property. This type of link building is known to be the most powerful way of garnering other web properties exposure with search engines for your own website or web properties benefit.
No Follow Backlinks– these are basically the opposite definition of what a DoFollow back link is. This type of link building is not as powerful as DoFollow contextual backlinks, but are still considered important as part of a well rounded and successful link building campaign
Authority Back Links– these are generated from high traffic and high PR established websites and web properties. Authority backlinks are typically on websites that have a high page rank of 6 or above, can be on an educational or government websites (.edu back links & .gov backlinks), or on any other web property that can be perceived as an authority website or web property that has an established presence with a healthy back link portfolio and established website history.

3)    Different b/w one-way ,two way, three way?

A) One way backlinks– they pass page rank and link juice to web properties. These types of anchor links are used for directing search engine crawlers “one way” to follow these  links back to your website, blog, social profile, media release or press release, videos, web 2.0 properties, do follow social bookmarking profiles, local directories, established web directories, and / or any other web property.
Two way (or) Reciprocal backlinks– this type of backlinking is the act of basically exchanging links between different websites and web properties. The phrase, “I’ll scratch your back, if you scratch mine” theory should help with explaining what a reciprocal back link is. This method is not as popular with search engines as it used to be back in the day because they see this as artificially boosting the page authority.
Three way backlinks - It is nothing but a traffic builder or search engine optimization. In a three-way link exchange, three different domains must be involved..A, B, C are three websites. it is considered negative. its a triangle A linking to B, B linking to C,and C linking to A.

4)    Why do not use two way back link method ?

A) A reciprocal link is a mutual link between two objects, commonly between two websites, to ensure mutual traffic. For example, Alice and Bob have websites. If Bob's website links to Alice's website, and Alice's website links to Bob's website, the websites are reciprocally linked. Website owners often submit their sites to reciprocal link exchange directories in order to achieve higher rankings in the search engines . Reciprocal linking between websites is no longer an important part of the search engine optimization process.
