Since 2005, I’ve spoken at more than 130 SEO and Internet marketing conferences including Pubcon, SMX, ClickZ, Digital Summit, and SEOktoberfest. If you’re shopping around for an SEO company, know that IMN wins on experience and knowledge. The average employee has been with us for over 9 years bringing our combined work experience to over 385 years! Compared to our Ninja army, I can’t believe that there’s a more experienced or tighter team of SEOs in the world. Today, we have 41 employees, most of them based in New York’s Capital District. When I started our Internet marketing company 23 years ago, it was just me and a dream. But our services today still remain true to our original mission. Over the years, the game has evolved the rules have changed, and how the game of SEO is played has changed. In 1999, I started this company with the mission statement, “We will work toward bringing in the greatest amount of relevant traffic to our clients’ websites, using the most ethical methods available.” That mission remains true today. It is also important to note that Google limits webmasters to 10 URL submissions per day.Īdditionally, Google says that the response time for indexing is the same for sitemaps as individual submissions.A Note From Jim Boykin CEO & Founder of Internet Marketing Ninjas Google states that for large URL volumes you should use XML sitemaps, but sometimes the manual submission method is convenient when submitting a handful of pages. This manual method of page discovery can be used when new content is published on site, or if changes have taken place and you want to minimize the time that it takes for search engines to see the changed content. Page submissionsĪlternatively, individual page submissions can often be made directly to search engines via their respective interfaces. These can help search engines find content hidden deep within a website and can provide webmasters with the ability to better control and understand the areas of site indexing and frequency. Sitemaps contain sets of URLs, and can be created by a website to provide search engines with a list of pages to be crawled. SitemapsĪnother way that search engines can discover new pages is by crawling sitemaps. Through this process of following links, search engines are able to discover every publicly-available webpage on the internet which is linked from at least one other page. These new URLs are added to the crawl queue so that they can be downloaded at a later date. Crawling and extracting links from pagesĬrawlers discover new pages by re-crawling existing pages they already know about, then extracting the links to other pages to find new URLs. You can find a full list of file types that can be indexed by Google available here. However, if the URL is a non-text file type such as an image, video or audio file, search engines will typically not be able to read the content of the file other than the associated filename and metadata.Īlthough a search engine may only be able to extract a limited amount of information about non-text file types, they can still be indexed, rank in search results and receive traffic. Search engines will normally attempt to crawl and index every URL that they encounter. However, the IP address that made the request can also be used to confirm that it came from the search engine – a process called reverse DNS lookup. Mozilla/5.0 (compatible YandexBot/3.0 +)Īnyone can use the same user agent as those used by search engines. Mozilla/5.0 (compatible Baiduspider/2.0 +) Here are a few examples of user agent strings used by search engines: The search engine bots crawling a website can be identified from the user agent string that they pass to the web server when requesting web pages. How can search engine crawlers be identified? For example, a page that changes on a regular basis may be crawled more frequently than one that is rarely modified. Search engine crawlers use a number of algorithms and rules to determine how frequently a page should be re-crawled and how many pages on a site should be indexed. The robots.txt file may also contain information about sitemaps this contains lists of URLs that the site wants a search engine crawler to crawl. Search engines use their own web crawlers to discover and access web pages.Īll commercial search engine crawlers begin crawling a website by downloading its robots.txt file, which contains rules about what pages search engines should or should not crawl on the website.
