The Basics Of Spiders - Web Crawlers
Do you like [tag]spiders[/tag]? You better if you want to get some natural visitors to your blog. It’s those little [tag]web crawlers[/tag] who are responsible for how you website is listed in the search engines. So it is in your best interest to understand how the spiders actually work and how they present information to the customer initiating a search.
There are basically two types of search engines. The first search engine is by robots called web crawlers or spiders.
[tag]Search Engines[/tag] release their spiders to index blogs and websites. When you submit your blog to a search engine by completing their required submission page, the search engine spider will index your site (this can take several months for some search engines). The spider is an automated programs that visit your blog and gather information such as post content, META tag information and title tags just to name a few. They also follow any links present on your site unless you instruct them otherwise.
After the spider has done it’s work, it returns all of your information back to a central depository, where the data is indexed. It will visit each link you have on your website and index those sites as well. By creating a sitemap, you can help the spiders find their way around your site.
The spider will periodically return to the sites to check for any updates to your site. How often depends on many factors which we will cover on another day. Remember that these little spiders are indexing millions of pages a day and it may take some time before they begin working on your blog.
When you ask a search engine to locate information, it is actually searching through the index which it has created and not actually searching the Web. Different search engines produce different rankings because not every search engine uses the same algorithm to search through the indices.
A [tag]search engine algorithm[/tag] will scan your website or blog for update frequency and the location of keywords on your page, but it can also detect “black hat keyword techniques” such as artificial [tag]keyword stuffing[/tag] or spamdexing. Then the algorithms analyze the way that pages link to other pages in the Web. By understanding the link structure of your site, the search engines are able to determine what your site is about. This why it is critical to have your links embedded in keyword rich tags.
There are so many aspects to website optimisation and it can sometimes become overwhelming. Just make sure you understand the basics of how the search engines work and you should be able to achieve some success. The only problem is the search engines are constantly changing their algorithms to make life a little tougher on us all.
