SEO Myths And Misconceptions
AdWords are NOT one of the factors related to weighing your site in the search results, AdWords customers do not receive special treatment in organic search.
Myth: Human algorithm filters
It is a known fact that humans evaluate websites before and after an algorithm update. Most Webmasters assume these quality raters are part of the algorithm filter that filters sites from search.
That is not true, the quality raters only evaluate the site and the algorithm results giving feedback to the algorithm team, feedback that could be used in future algorithms, which does get used, and so does info from feedbacks and spam reports.
Myth: Algorithm reconsideration required
Reconsideration requests for algorithm updates/filters are not necessary and will not work, algorithms are handled by programs and not humans.
Therefore, the program itself algorithmically determining your rankings.
Myth: Immediate recover after an algo filter
Recovery will not occur immediately after you make changes to your site, they will only occur after an algorithm refresh or update which could take a month to 3 months, depending on when they re-run the algorithm.
A site very seldom fully recovers. Depending on the changes made, will depend on your new rankings.
Myth: robots.txt prevents pages been crawled
That is incorrect If the crawler picks up the links on other sites, it will crawl those pages and index them.
If you want to permanently block pages from the index, use the noindex meta tag in the head section of your document.
Myth: Dynamic URLs cannot be crawled
That is a myth, Google crawl static and dynamic URLs and can interpret different parameters.
The crawling issue will only arise if you remove information by hiding parameters and making them look static.
