 I get asked a lot of questions. Below are answers to the more commonly asked
 ones:
 
 Meta Tags - Spamming - Submitting - Other
 
 Meta Tags
 
 Q. What are the maximum lengths for the description and keyword meta tags?
 
 There aren't set official lengths. Rather, each search engine only makes use of 
 a certain number of characters. Generally, stick with 200 characters for your
 description and 1000 characters for keywords, and you'll be fine. Going longer
 than this does not disqualify your tags. The extra information simply won't be
 indexed, or in the case of a description tag, be displayed on screen. Also be
 sure to read the More About Meta Tags page for further help.
 
 Q. How often can I repeat words in meta tags?
 
 There are no published rules. See the More About Meta Tags page for some general
 advice that may help you avoid problems.
 
 Q. Can you make search engines revisit your site more often by using the meta
 revisit tag?
 
 The meta revisit tag looks like this:
 
 <META NAME="revisit" CONTENT="15 days">
 
 The idea is that by specifying a time span, such as 15 days in the example
 above, you'll make the search engines revisit your site as often as you specify.
 However, none of the major search engines recognize this tag. They will not
 revisit according to any time span you specify within it. Instead, they'll come 
 back according to their own schedules.
 
 Q. Does the title tag have to come before meta tags?
 
 No, and for more about this issue, especially for FrontPage users, see the More 
 About Meta Tags page.
 
 Q. Some search engines use the first text found within the body tag as the
 "description" text they display for that page. They disregard the meta
 description tag. How can I control hide my page summary for these engines?
 
 You can make an image the first thing that appears after the body tag and insert
 your description as ALT text for that image. That's especially helpful for the
 Lycos crawler. You might also make a comment tag with your description appear
 right after the body tag. Finally, you can simply ensure that the first 200
 characters or so of HTML text after a body tag contains the description you
 want. Despite these attempts, there will still be some search engines like
 Google that make their own decision on what to use for a description, rather
 than using your meta description tag or the alternatives I've suggested.
 
 Q. If I have the word, "marketing" in my meta tag keyword list, and someone
 enters the word "market," can most search engines today figure out that "market"
 is contained in "marketing," or should I include both market and marketing in my
 tag.
 
 You should include both forms, and not just within the keywords tag but also in 
 the page copy itself. That's far more important. While some search engines may
 use "stemming" to understand that marketing is a form of the word "market," you 
 cannot depend on this and you may still generally find that they will give
 preference to exact matches.
 
 Spamming
 
 Q. Where can I find the "rules" about what search engines consider to be
 spamming?
 
 The What Is Search Engine Spamming? page summarizes some of the more common
 spamming tactics that search engines may penalize for. There is also information
 about what is, and isn't, acceptable on the Search Engine Features and the
 Search Engine Design Tips pages. These have been developed from constant contact
 with sources at the search engines. Some of the search engines also provide
 information about spamming within their help pages, though this is usually
 sparse.
 
 Q. I know HTML redirects with the meta refresh tag are bad, but what about
 JavaScript "location" assignments? These are often used to provide browser
 specific pages. Will this cause my listing to be rejected by some engines?
 
 A. In general, any type of redirection is bad. However, I've only ever received 
 reports of Go.com having problems with Java redirection.
 
 Submitting
 
 Q. How often should I resubmit?
 
 A. I operate on the "if it ain't broke, don't fix it" rule. If your site is
 listed well with search engines, then I don't see great advantages to
 resubmitting. However, if you see your traffic drop from a particular search
 engine, then resubmitting to that search engine can make sense.
 
 Q. Will I get in trouble submitting other people's pages to the search engines?
 
 What type of trouble, morally, legally or with the search engines themselves?
 The answer depends on the type of page you are resubmitting. If you submit a
 page that a search engine doesn't currently list, for purposes of helping to
 improve its listings, you should have no problems. Similarly, if you submit a
 page that no longer exists, in order to help a search engine remove it from its 
 listings, that also poses no problems.
 
 Some webmasters submit pages that have changed since the search engine has last 
 visited them, especially if these are competitor pages that have good rankings
 for particular terms. A search engine should revisit these anyway, so it would
 be hard for anyone to argue that you've done any harm. Similarly, some
 webmasters submit pages that have current listings, simply to see if they can
 cause a ranking to drop.
 
 Morally, I don't like this, nor do I think I'm alone in that. However, other
 people may feel this is perfectly fine. Legally, there's never been a case I
 know of involving submission of other people's pages. Potentially, one could be 
 raised, if the web site owner could prove you did the submission and equally
 convince a court that your submission caused them real harm. As for the search
 engines, if you were to embark on a large scale resubmission of current pages,
 they probably would not look upon this favorably. It's unclear how they'd be
 able to track this back to an individual, though. At best, they might block your
 IP address. That only hurts those with dedicated Internet connections. People
 connecting by modem get a different IP address each time they connect.
 
 Finally, some people may resubmit many pages from a site in hopes of convincing 
 a search engine that the site is attempting to spam them. I find this morally
 wrong, and I think most people would also agree with this. Legally, it would
 make for a stronger case to show harm, as you are attempting to harm another
 sites reputation. The search engines themselves would definitely not like this
 activity.
 
 Q. If I have subdomains for different web sites, will these be seen as separate 
 web sites by search engines?
 
 Let's talk definitions, first. There are top level domains, such as .com, .net
 and .edu. When site owners register a domain, technically these are subdomains
 of these top level domains. By generally, we refer to these as root domains. For
 instance, this would be a root domain:
 
 yahoo.com
 
 Sometimes people create additional "subdomains" that are extensions of their
 root domains. For instance, these are all subdomains:
 
 computers.yahoo.com
 mail.yahoo.com
 my.yahoo.com
 
 All the major search engines will treat these subdomains as separate sites, even
 though they use the same base domain. That means they can each be submitted
 separately. This also offers some advantages to those who run particularly large
 web sites. By breaking your site up into subdomains, you may find more pages
 overall get indexed.
 
 See also the Submitting To Search Engines & Encouraging Crawlers page.
 
 Other
 
 Q. Do search engines sell keywords?
 
 Only GoTo.com sells placement within its main search results. None of the other 
 major search engines do this. However, they do sell keyword-linked banner
 advertisements. For more information, see the Pay For Placement page.
 
 Q. I thought the Inktomi (soon Google) search engine was used at Yahoo to spider
 sites, but my site still isn't listed.
 
 Yahoo has two sources of information. By default, you are shown listings from
 its own index, which is compiled by humans. If there are no matches from that
 index, then you are shown matches from the Inktomi index, which comes from
 spidering the web. You also are shown these results after seeing any available
 Yahoo index results. You will only appear in the first index if you have
 submitted to Yahoo and been accepted into it. See the How Yahoo Works page for
 more tips about this.
 
 Q: Is there a standard out there for how much search engine traffic should come 
 from optimization efforts? In terms of web site traffic, is there a percentage
 one should expect from search engines?
 
 A: There are no standards that I know of. Every site is different. Some may
 naturally attract more traffic from search engines than others. Personally, I
 think having 30 to 50 percent of your traffic from search engines is fine. More 
 than that amount, and you are probably too dependent on search engines. Less
 than that, and you can probably do better.
 
 Q. In terms of the "Find Similar" feature that some search engines offer, how
 does it work? What process does the search engine follow in order to carry out
 this function?
 
 In most cases, the search engine will look at the document you selected, then
 seek out other documents that seem to fit its particular usage of words. In some
 other cases, such as at AOL Search, you will be taken to where that page lives
 within the human-compiled directory -- which means you can see other pages like 
 it, as determined by humans. For more about Find Similar features, see the
 Search Assistance Features page,
 http://searchenginewatch.com/facts/assistance.html.
 
 Q. Do search engines read Flash content?
 
 No. If you have a page that only has Flash content on it, the search engines
 will essentially see a blank page. It is especially important to avoid doing
 this on your home page, if it is the root page of a web server. That is because 
 root pages are ranked more highly by most search engines than inside pages. Not 
 having solid HTML content on your root page is like handing out a blank business
 card.
