What Is Preventing the Crawling Method in Search Engine Optimization

1. Avoid flash

Flash isn’t inherently bad. When used properly, it will enhance a visitor’s experience. however, your website shouldn’t be designed entirely in Flash, nor ought your website navigation be done only in Flash. Search engines have claimed for some years currently that they’re higher at crawling Flash, however, it’s still not a substitute for permanently crawlable website menus and content.

2. Avoid AJAX

The same concepts mentioned higher than relating to Flash apply here to ajax. It will raise your site’s user expertise, however, mythical beings have traditionally not been visible to go looking engine crawlers. Google offers tips to help create AJAX-based content crawlable, however, it’s complicated, and therefore the SEO “best practice” recommendations stay the same: Don’t place necessary content in ajax.

3. Avoid complex java script menus

Java script is another technology that search engines optimize for getting higher at crawl however remains best avoided because of the primary technique of presenting website navigation. Back in 2007, Google explained:

While we are operating to raise perceived JavaScript, your best bet for making a website that is crawlable by Google and different search engines is to produce Html links to your content.

That’s still easiest observe today: ensure your site navigation is presented in simple, easy-to-crawl HTML links.

4. Avoid long dynamic URL

That’s a very easy dynamic URL and today’s search engines haven't any trouble creeping one thing like that. However, once-dynamic URLs get longer and a lot more complicated, search engines optimization (SEO) could also be less able to crawl them (for a range of reasons, one in all that is that studies show searchers prefer short URLs). Google’s webmaster facilitate page says it well: “…be aware that not each search engine spider crawls dynamic pages further than static pages. It helps to stay the parameters short and therefore the variety of the few.”

5. Avoid session IDs in URLs

This is an off-shoot of the previous item but should be mentioned separately. Search engines optimization (SEO) don’t wish to crawl and index URLs that have a session ID. Why? As a result, despite the fact that the session ID makes the address completely different anytime the spider visits, the particular content on the page is the same. If they indexed URLs with session IDs, there’d be a lot of duplicate content disclosure within the search results.

6. Avoid code bloat

By “code bloat,” I’m referring to things wherever the code needed to render your page is dramatically more substantial than the particular content of the page. In several cases, this can be not one thing you’ll need to worry about—search engines have gotten higher at handling pages that have significant code and small content. Code bloat isn’t a problem until it’s a big problem…but it’s something website owners should be aware of.

7. Avoid robots.txt blocking

First, you’re not needed to own a robots.txt file on your website; variant websites do simply fine while not one. However, if you employ one (perhaps as a result of you wish to create certain your Admin or Members-only pages aren’t crawled), use caution to not fully block spiders from your entire website.

8. Avoid incorrect XML sitemaps

An XML sitemap lets you provide a list of URLs to look engines for doable crawl and indexing. They’re not a replacement for proper on-the-scene navigation and not a panacea for things wherever your website is tough to crawl.

If enforced properly, an XML sitemap will facilitate search engines to become aware of the content on your site that they'll have missed. But, if enforced incorrectly, the XML sitemap may truly deter spiders from crawling.

If you’re curious, I’ve only once instructed that a consumer use XML sitemaps, that was a website with upwards of fifteen million pages. If you wish to be told additional regarding XML sitemaps

If you take care of all the problems on top of, you'll rest assured that you’ve created it as simply as attainable for search engines to crawl and index your website.
