 The students as any business and any domain have their own terms, have their own terminology. So in this module, I will cover some of the key terms, glossary and terminology with reference to search engine optimization. In the text, 200 search terms are given. It's not possible to cover all of them in one module. So I have shortlisted about 49 of those terms and terminology and I will cover some of the key terms from among those 49. So let's go and deep into it above the fall above the fall is what the user sees when they visit your page without scrolling the page. And if you put too many advertisements without the scrolling the Google search engine and their algorithm as a matter of fact penalizes search pages. Then is Bidu. Bidu is a Chinese search engine which was launched in year 2000. And of course, it is very popular in China and it mostly indexes the Chinese websites. Bouncing is the search engine for via the Microsoft broken link. Broken link is a link which generates four or four error. What is that error that the link is there? But when I click on that link, that link is not connected to any page. That is a broken link. Bounce rate. Bounce rate is people land on my page. It is a percentage and without further investigating or going deep into my webpage or clicking at a link in my webpage, they leave bounce rate. They come. They don't do anything and they go bounce rate clickbait clickbait is there is a link and that link is promising something interesting something rewarding something enticing. But it is not there. So the text is there a picture is there something maybe a video is there. But when I click on it, it leads to some other place. It generates and results in something else, which was not what was promised. That is a bit. Then is conversion rate. Conversion rate is again people land on my page. And how many of those people as a percentage do what was required from them to do. For example, people land on my page and I asked them to give some information. And I asked them to participate in a survey. And I asked them to perform a certain operation to get registered. Okay. How many of them get registered with reference to how many came over there. Crawler. Crawler is the software which automatically moves over the web moves over my website and looks at the information which is used to index the web and my web page. Then is dead end page. Dead end page is obviously the page where I can come but there is no place. There is no link going out of anywhere to that page. That's a dead end page. Deep link. Deep link is that these are my web pages. Okay. And I can go and land over here. I can go and land over here without sequentially moving through the pages. Duck duck go. Duck duck go is a search engine which is popular by virtue of the fact that it preserves the privacy. In my experience in my humble experience it does not performs in terms of response and results like other search engines but it preserves my privacy. It does not shares it with other people. Duck duck go. Findability is how what is the measure of getting or found my page over the internet over the web. Google analytics is a tool which use, which can use by you to analyze the user behavior when they visit your website. And of course there is certification of Google analytics also. Google boot is the crawler by Google. Google Trends is a free analysis service which analyzes what keywords are being used over the internet. What people are searching for. Guess blogging is that I write blogs for you and you in term link to my page. This is not desired by Google. Hidden text is I have put lots and lots of text in my web page okay. But of course it is not visible to the visitors and I am hoping that based upon those text which is hidden I get a high ranking by the search engine. Keywords stuffing is also same as this hidden text that I put lots and lots of keywords hoping that my page gets high position in the search results and those keywords may have nothing to do with the contents of my page actual contents of my page. This is not desired by Google search. Link bit is the same as before that it is promising something but it is not there. Link form is that number of people okay number of these are linking to each other. These are linking to each other in the hope of creating lots of links which falsely makes their web page popular their website popular. A link velocity is how fast a link is or how fast a site is getting linked. If it is if there is high link velocity it means there is spam log file which is recording all the data. Then of course this lot of things over here organic search is the results which appear on your screen when you perform a search over a search engine and rich snippet is the text which is shown which you store with your web page when somebody comes over there and it gives a very brief intro about it and then of course is robots.txt it is a text file which I place on your website which you place on your website are giving certain directions to the crawlers or to the robots and WordPress is a very popular content management system you can create wonderful websites using WordPress I am not advertising WordPress but this is a fact and Yandex is a Russian search engine which has been around for quite a while. So you see there is a lot of terminology and there is a lot of glossary which you need to know and you need to understand also because knowing is not sufficient applying is the key that's the message for you thank you for your time.
