Spiders, robots and crawlers?

can anyone explain what are spiders, robots and crawlers?
what these have to do with seo?. please reply me.

thanks in advance.

They're all different names for the same thing. They don't affect SEO directly. The search engines use bots to crawl webpages to add to their index and then rank them. So you need to make sure your website is able to be crawled by bots if you want to be ranked in the search engines.

Oh I see,
thanks stymiee,

Me and brothers were decided to launch a content website next month. Already we have two content websites each having more than 600 a total of links in all search engines. But these sites are not producing that much revenue. So we have taken this decision. Both of them asked me to do the job of optimizing and they have given me a target of $100 in Google Adsense account withing 5 months. I am in a tight corner that I have to concentrate in my UG studies also. They both work for another private company. I really need help from SEO professionals and SEO specialist that How can I achieve the target they have given me? What are all the initial steps that I should follow? How to bring traffic from Google? whether using Keyword optimization, more contents or links. If your answer lies in anyone of these please explain me in detail! And most important question, On which topics I have write articles? Specify Which topic is top in world searches? Please I am expecting answers for all these questions! Thanks whole heartedly to those who render!

While this forum is good for asking questions, if you're just starting out you need to do a LOT more research on this before just asking a general "how to do it?" question like this. It takes a lot of time, energy and work to get a site ranking well. Five months may be enough, it may not be. Depends on how much effort you can put into it over that time.

The best place to look and research is probably SEOChat so go there and hunt around. You can also ask questions on their forums.

Google is a fully automated search engine that uses software known as "spiders" to crawl the web on a regular basis and find sites to add to our index. . Different search engines have different names for this.
A robots.txt file provides restrictions to search engine robots (known as "bots") that crawl the web. These bots are automated, and before they access pages of a site, they check to see if a robots.txt file exists that prevents them from accessing certain pages...

Usually when the Googlebot finds a page, it reads all the links on that page and then fetches those pages and indexes them. This is the basic process by which Googlebot "crawls" the web.

Let me know any confusion....

Just to add to what eimee said, if you want to exclude some pages from the crawlers (for example some pages that you are using just to organise your own files) then you need to edit the robots.txt file on your web server.

The best way to increase revenue via Google Adsense is by developing viable (unique) content...

What is the content subject of your sites?

all three are same thing, this is the progamm which find your site and store your site's information to search engine's database.

I think to delve deeper into the SEO in just 5-6 months you need lots and lots of reading about the subject itself and experimenting with what you are reading to get it affirm. There are lots of myths about seo spreaded all over the net, so be careful while applying whatever you read. Many newbies fall in danger [I mean their site got banned] while applying some unethical/black hat seo techniques. Though seo is a challenging and interesting thing, I liked experimenting with it and finding out what search engines are up to.

And most of all get some high quality links. If you would like to get started feel free to place a link from one of my two sites: www.1st-casinos.co.uk and www.spreadbetting-uk.co.uk. The ADD URL link is at the bottom of the page.

Good luck with the SEO. Its rewarding when you start to see the results and your traffic goes up.

If you want to do well in PPC on a small budget you need to hit the long tail.

The long tail is the more specialized keywords that have less competition and are searched a lot less. This means more relevant searches from people looking for exactly the stuff you want to sell/service you want to offer hence higher conversion rates.

For example if you sell ecommerce services you could waste your budget on high priced keywords like ecommerce, or e-commerce bare in mind these are 2 different terms, or you could go for ones like ecommerce solutions or unique e-commerce soultions You have to do your keyword selection to decide whats best for you and your site. Don't use ecommerce solutions if you don't offer ecommerce services

This way you will maximize your ROI on a budget.

Other wise check out the seochat forum or buy a book, but I would do both.

Hope it works out.
