Suggested January 2024 Yahoo Answers Site Match Inclusion Questions
Yahoo has recently drawn heat over its new Site Match paid inclusion system used to add sites to the new Yahoo Search index. The Yahoo Team recently answered a lot of the questions posed onthe Jim World Search Engine Marketing Forum about Site Match to clear up some of the doubts that may be lingering in the search engine marketing community. Here is the list of Yahoo Site Match questions from search engine marketers, and Yahoo´s responses.
Q. Why should I pay for Site Match if my site is already indexed or may soon be indexed for free?
A. Our primary goal is to discover and include all content on the web through our free web crawling process. Today 99% of the information in the index comes from the free crawl. Site Match, however, provides many benefits to content providers even when their content is already indexed.
Both content providers and search users benefit from greater interaction between sites and the search engine. In fact, for several years a good number of message board posters have been asking for greater clarity from search engines about how to participate and what the “rules” are. The Site Match program addresses this additional need by providing a value-added service that focuses on providing a clearer, more consistent way to interact with Yahoo! Search. Specific components include: the ability to proactively submit content to us, frequent refresh, quality review, detailed reporting, and support when problems arise. The program is cost-effective, easy to manage, and includes the ability to control total cost.
2. A clearer, more consistent way to interact with Yahoo! Search for content providers who historically have been subjected to unpredictable changes in the way their content has been discovered and presented by search engines.
– Sites that are looking for more user data and clearer, more consistent interaction with the search engine
Yahoo! believes these benefits are of value to many businesses, and the considerable demand for the program we’ve seen thus far would seem to support that. However, the program may not be valuable to everyone. We understand this – not everyone wants or needs the value-added service that Site Match offers. That’s OK, because it’s likely that we already have your web pages through our regular crawl, and if we don’t yet, we’re working to get them over time. This is a cornerstone of our mission to provide the highest quality search experience on the internet.
– You don’t think you need more user data on search performance
If this describes your site, then the free crawl may be adequate for you and you don’t need the added value of the Site Match programs.
Q: What if I can’t afford this program? Will you have a lower priced program in the future?
Q. Will Yahoo! Search results sacrifice quality by favoring sites that pay for the Site Match program?
A. Absolutely not. Since its inception, the Yahoo! Search mission has been to provide the highest quality search experience on the Internet. The motivation behind this is simple: if we do not provide the highest quality search experience we will not be providing users with an incentive to stay and continue to use our product. It is the quality of our results – as defined by their relevance, comprehensiveness, freshness and presentation – that will ultimately lead to our success in search and we will not compromise the quality of these results.
Q. If I participate in Site Match, will my site be “banned” from the search index?
A. No. The Site Match and crawling systems are separate (one doesn’t affect content in the other) and participation in Site Match does not impact the efforts of our crawlers to index all of your content. For instance, if you submit 1 page to Site Match, other pages that may be in the regular index will not be affected.
In addition, content from both systems is reviewed and evaluated against the same criteria to ensure all content meets a consistent, high quality standard. If you joined the Inktomi Search Submit program, for example, you may have been reviewed. If problems were discovered, your site may have been partially or entirely removed from the search index. The same thing happens to sites that have been discovered through the free crawl process. If problems were discovered, your site may have been partially or entirely removed from the search index. Any review-related penalty is solely designed to ensure the best experience for our users, not to encourage ongoing participation in our inclusion programs. Also, removal of URLs from Site Match will in no way impact our crawlers’ efforts to index those URLs.
Q. Will the Inktomi index be merged with the new Yahoo! Search index before Inktomi disappears?
A: Today there is a single, new Yahoo! Search Technology (YST). YST powers Yahoo! Search and in the coming months will also be powering search solutions for all our partners. Yahoo! Slurp, Yahoo!’s new crawler, is already reaching and indexing more of the web than any of our prior technologies.
Q. What happens to my site if I previously participated in a paid inclusion program (e.g. Inktomi Search Submit)?
A: If you previously participated in a subscription-based paid inclusion program from Inktomi, AltaVista or FAST, you have the option of continuing your current subscription in which case the terms of your subscription will not change. This will continue until the end of your subscription. As an added bonus, your participation will also extend to Yahoo! Search results until April 15, 2004. Note that Inktomi Index Connect (feed-based) customers may continue participating in the full network of portals, including Yahoo!
Q. Does Site Match allow URLs to be targeted to specific countries?

Site miners will match medicine and engineering New program spots potential for life-saving collaborations

George O’Connor, a School of Medicine professor and asthma researcher at the Pulmonary Center, appreciates the value of serendipity. It was, after all, a fortuitous dinner with his Boston University colleague Bela Suki during a National Institutes of Health symposium in Washington, D.C., last year that led to an ongoing collaboration on a mechanical ventilation system that could one day help save the lives of patients with respiratory failure.
Suki is an associate professor of biomedical engineering at the College of Engineering, but news of his research never traveled across campus to O’Connor until they met in Washington.
Now, O’Connor is trying to identify the potential for similarly valuable collaborations, whose genesis need not be dependent on chance. He is one of two newly appointed University “site miners,” faculty members who will devote 20 percent of their professional time to identifying and cultivating research partnerships between engineers and clinicians that are intended to help translate promising technologies into better patient care. Mark Grinstaff, an ENG associate biomedical engineering professor and College of Arts and Sciences associate chemistry professor, is the other new site miner.
“The job of the site miners is to sift through the various projects and expertise ongoing at each campus, to try and mine the gems that have some sort of natural affinity for one another,” says Mark Klempner, a MED professor and the associate provost for research at the Medical Campus, which along with the College of Engineering and the Office of Technology Development is funding the positions. Every two years, an administrative committee will appoint one clinical site miner from the Medical Campus and one engineering site miner from the Charles River Campus.
“I think there’s a tremendous opportunity, because of the resources that are here, both in engineering and the medical school,” says Grinstaff, who researches synthesized biomaterials with uses ranging from sealing eye wounds to delivering cancer drugs.
Grinstaff and O’Connor are scientific matchmakers who will seek out the technologies that hold the most promise for improving health-care practice and vice versa, looking into clinical challenges that might have technology-based solutions. They’ll meet with each other to discuss what they’ve found, and they’ll arrange meetings where potential collaborations can be discussed and critiqued by the engineers and clinicians themselves.
But the site miners’ work will not end there. “It’s not just about identifying innovative ideas,” explains Kenneth Lutchen, an ENG professor and biomedical engineering department chairman. After promising matches are made, the site miners will help researchers apply for grants needed for further research such as making prototypes that could be used in human trials.
Lutchen says the site miners are part of ongoing, University-wide efforts to “help move innovation from the lab to the bedside.” These efforts were recently given a boost by the Wallace H. Coulter Foundation, which awarded Boston University a five-year, $2.9 million grant to foster translational research in biomedical engineering, the funding source that O’Connor and Suki hope will help fund human trials of the mechanical ventilation system.
“There is a lot of potential that just wasn’t being tapped,” says O’Connor, who adds that the separation between the two campuses made it easy to overlook the possibilities for collaboration. “They’re over there, and we’re over here, and we weren’t really aware of what everybody was up to.”
Nevertheless, the human connections are just as important as money when it comes to finding technology that can improve patient care, says Ashley Stevens, director of the Office of Technology Development. Stevens says that about two thirds of the inventions that his office works to license and bring to market originate from either the Medical Campus or the College of Engineering. He even gives the Boston University Shuttle (the BUS) some credit for bridging those two sources of innovation since it began running more frequently and reliably in the fall of 2004.
“It’s such a people process,” Stevens says, and that’s where Grinstaff and O’Connor think they’ll have the biggest impact.

You will need to replace the sample configuration settings with your own VPN settings.How do you configure a Linux system to use a static MAC address for a network interface?
To configure a Linux system to use a static MAC address for a network interface, you will need to edit the network configuration file for that interface. The location of this file may vary depending on your distribution, but it is usually located in the /etc/network/interfaces directory. Here is an example of how to configure a static MAC address for the eth0 interface −$ sudo vi /etc/network/interfaces auto eth0 iface eth0 inet dhcp hwaddress ether 00:11:22:33:44:55
In this example, we have assigned the MAC address 00:11:22:33:44:55 to the eth0 interface.How do you configure a Linux system to use a static IP address for a wireless network interface?
To configure a Linux system to use a static IP address for a wireless network interface, you will need to edit the network configuration file for that interface. The location of this file may vary depending on your distribution, but it is usually located in the /etc/network/interfaces directory. Here is an example of how to configure a static IP address for the wlan0 interface −$ sudo vi /etc/network/interfaces auto wlan0 iface wlan0 inet static address 192.168.1.100 netmask 255.255.255.0 gateway 192.168.1.1 wpa-ssid myssid wpa-psk mypassword
In this example, we have assigned the IP address 192.168.1.100 to the wlan0 interface, along with the netmask, gateway, SSID, and password for the wireless network.How do you configure a Linux system to use VLAN tagging?

In the case of viewDidLoad, this is mainly called when the hierarchy loading process for the view controller has been completed and the records have been loaded into memory successfully. Developers can override this method to process the extra initialization on views implemented from nib files.
In the case of viewDidAppear, this is mainly called when the animation process, which is involved in the initial view appearance, has been completed. Developers can override this method to implement tasks that do not interfere with the ongoing animation view process. So, when there is a rapid change in data or view of the animation process, viewDidAppear is an excellent method to implement the system functionalities.Q4. Explain Completion Handler and Blocks from an iOS perspective.
Blocks are a language-level feature implemented along with C and C++ languages. With regard to the methods or functions, these produce distinctive code portions that can be passed. These can be processed later depending on the system’s capabilities and are not limited to real-time executions. It also implements the codes and displays the same in a much cleaner representative way.Q5. Explain StoryBoard and Programmatic UIView from an iOS perspective.
Developers can construct a view and add new views to it programmatically for StoryBoard. They primarily use StoryBoard for quick UI representation based on appropriate design specifications. It also produces the end-to-end visualization of the entire system process. But in the case of a duplicate handling process, StoryBoard implementation becomes challenging to update as per the system functionality.
In the case of Programmatic UIView, it generally possesses a bit longer and more tedious approach than StoryBoard. Here it gives a steadier response to the current code and the corresponding views based on the system functionality. It also develops a branching approach to the fundamental principles present and thus becomes more easily unit testable.Part 2 – iOS Interview Questions (Advanced) Q6. What are the different types of iOS states?
The different types of iOS application states are:
Idle/Not Running State: In this step, the App should remain idle or not running.
Active State: In this step, the App should stay moving and should work as per the user inputs and system functionality.
In-Active State: This step requires the App to remain inactive, which means that it can be executed in the background, but it should not perform any UI-based functionality.
Suspended State: In this state, the App should remain in balanced mode. Here, the app should not execute any code, and its ongoing execution should remain in exact stop mode.Q7. Which property returns initialized objects?
Answer:Q8. Explain App Id and Bundle ID from an iOS perspective.
These are some of the more difficult iOS interview questions. The string “App Id” has two parts. In this situation, the participating development team mostly uses it to track the progress of one or more applications. They use the Bundle Id to identify the particular program in question.Q9. Explain reuseIdentifier.
This identifier sorts group parameters to implement identical rows in the UITableView artifacts.
Easy development concerning UI standardization.
Very smooth operating system, and thus, the quality usually is higher than Android.
The size of the apps is generally on the higher side than that of Android OS.Recommended Articles
