A crawler is a computer program that is used by search engines to rank the pages on the internet. This tool is extensively used by search engine optimization applications to find out the best possible result for what the user is looking. A web crawler is also known as a spider or a web robot.
The crawler uses many algorithms to rank a website. When you are designing a website, you should keep following things in your search engine optimisation techniques. Spiders like the text more than the code. It is easier for the spiders to spot the text content more than the coded part. So when you are trying for search engine optimization of your site, try to include as much text content as possible to boost your search engine marketing campaign. Text is spotted easily. You should make your web content enriched with keywords. When the user types anything in the search tab, the crawler looks for the web content that includes those keywords. If your web page has those keywords, the crawler keeps a track of those web pages. There is a web server maintained by the search engine optimization mechanism. This server has a list of all the relevant web pages based on what the user is looking for. Thus, if you’re search engine optimization content has the keyword that the user is looking for; it is selected by the spider.
When you are doing SEO of your website, ensure that you search for the keywords that are relevant to your website. You can use tools like Google Adwords to find out the keywords that are highly searched. Use these Google SEO keywords in your website. Also, make it a point to highlight the keywords because highlighted words are picked by the crawler quickly. Also, make it a point to include the keywords that are related to the main keyword as you can never predict as to what the users will type. While doing the search engine optimization of the site, make sure that the keyword density are in the range of 3%-7%. Do not think that more the keywords, better as there are tools that can check if the keywords used are only to fool the crawlers. In that case, your site may fall down the index list.
Another important search engine optimisation strategys to include as many backlinks as possible. If you have more links towards your site, it will give the impression to the crawler that the website has some important data that can be useful. It adds to the authority of the website. When you are including the content in your search engine optimization strategy, try for original content. The crawler can make out if your search engine optimization content is flipped from somewhere else. If you have too many animations and pictures, it will work against your search engine optimization effort. Also ensure that your search engine optimization includes ALT Tabs for images as crawlers cannot view the pictures.
